Unfortunately, the POSIX TZ string takes - a form that is hard to describe and is error-prone in practice. - Also, POSIX TZ strings can't deal with other (for example, Israeli) - daylight saving time rules, or situations where more than two - time zone abbreviations are used in an area. - - The POSIX TZ string takes the following form: - - stdoffset[dst[offset],date[/time],date[/time]] - - where: - - std and dst - are 3 or more characters specifying the standard - and daylight saving time (DST) zone names. - Starting with POSIX.1-2001, std and dst may also be - in a quoted form like ""; this allows - "+" and "-" in the names. - offset - is of the form `[-]hh:[mm[:ss]]' and specifies the - offset west of UTC. The default DST offset is one hour - ahead of standard time. - date[/time],date[/time] - specifies the beginning and end of DST. If this is absent, - the system supplies its own rules for DST, and these can - differ from year to year; typically US DST rules are used. - time - takes the form `hh:[mm[:ss]]' and defaults to 02:00. - date - takes one of the following forms: - Jn (1<=n<=365) - origin-1 day number not counting February 29 - n (0<=n<=365) - origin-0 day number counting February 29 if present - Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12) - for the dth day of week n of month m of the year, - where week 1 is the first week in which day d appears, - and `5' stands for the last week in which day d appears - (which may be either the 4th or 5th week). - - Here is an example POSIX TZ string, for US Pacific time using rules - appropriate from 1987 through 2006: - - TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00' - - This POSIX TZ string is hard to remember, and mishandles time stamps - before 1987 and after 2006. With this package you can use this - instead: - - TZ='America/Los_Angeles' - -* POSIX does not define the exact meaning of TZ values like "EST5EDT". - Typically the current US DST rules are used to interpret such values, - but this means that the US DST rules are compiled into each program - that does time conversion. This means that when US time conversion - rules change (as in the United States in 1987), all programs that - do time conversion must be recompiled to ensure proper results. - -* In POSIX, there's no tamper-proof way for a process to learn the - system's best idea of local wall clock. (This is important for - applications that an administrator wants used only at certain times-- - without regard to whether the user has fiddled the "TZ" environment - variable. While an administrator can "do everything in UTC" to get - around the problem, doing so is inconvenient and precludes handling - daylight saving time shifts--as might be required to limit phone - calls to off-peak hours.) - -* POSIX requires that systems ignore leap seconds. - -These are the extensions that have been made to the POSIX functions: - -* The "TZ" environment variable is used in generating the name of a file - from which time zone information is read (or is interpreted a la - POSIX); "TZ" is no longer constrained to be a three-letter time zone - name followed by a number of hours and an optional three-letter - daylight time zone name. The daylight saving time rules to be used - for a particular time zone are encoded in the time zone file; - the format of the file allows U.S., Australian, and other rules to be - encoded, and allows for situations where more than two time zone - abbreviations are used. - - It was recognized that allowing the "TZ" environment variable to - take on values such as "America/New_York" might cause "old" programs - (that expect "TZ" to have a certain form) to operate incorrectly; - consideration was given to using some other environment variable - (for example, "TIMEZONE") to hold the string used to generate the - time zone information file name. In the end, however, it was decided - to continue using "TZ": it is widely used for time zone purposes; - separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; - and systems where "new" forms of "TZ" might cause problems can simply - use TZ values such as "EST5EDT" which can be used both by - "new" programs (a la POSIX) and "old" programs (as zone names and - offsets). - -* To handle places where more than two time zone abbreviations are used, - the functions "localtime" and "gmtime" set tzname[tmp->tm_isdst] - (where "tmp" is the value the function returns) to the time zone - abbreviation to be used. This differs from POSIX, where the elements - of tzname are only changed as a result of calls to tzset. - -* Since the "TZ" environment variable can now be used to control time - conversion, the "daylight" and "timezone" variables are no longer - needed. (These variables are defined and set by "tzset"; however, their - values will not be used by "localtime.") - -* The "localtime" function has been set up to deliver correct results - for near-minimum or near-maximum time_t values. (A comment in the - source code tells how to get compatibly wrong results). - -* A function "tzsetwall" has been added to arrange for the system's - best approximation to local wall clock time to be delivered by - subsequent calls to "localtime." Source code for portable - applications that "must" run on local wall clock time should call - "tzsetwall();" if such code is moved to "old" systems that don't - provide tzsetwall, you won't be able to generate an executable program. - (These time zone functions also arrange for local wall clock time to be - used if tzset is called--directly or indirectly--and there's no "TZ" - environment variable; portable applications should not, however, rely - on this behavior since it's not the way SVR2 systems behave.) - -* These functions can account for leap seconds, thanks to Bradley White. - -Points of interest to folks with other systems: - -* This package is already part of many POSIX-compliant hosts, - including BSD, HP, Linux, Network Appliance, SCO, SGI, and Sun. - On such hosts, the primary use of this package - is to update obsolete time zone rule tables. - To do this, you may need to compile the time zone compiler - `zic' supplied with this package instead of using the system `zic', - since the format of zic's input changed slightly in late 1994, - and many vendors still do not support the new input format. - -* The UNIX Version 7 "timezone" function is not present in this package; - it's impossible to reliably map timezone's arguments (a "minutes west - of GMT" value and a "daylight saving time in effect" flag) to a - time zone abbreviation, and we refuse to guess. - Programs that in the past used the timezone function may now examine - tzname[localtime(&clock)->tm_isdst] to learn the correct time - zone abbreviation to use. Alternatively, use - localtime(&clock)->tm_zone if this has been enabled. - -* The 4.2BSD gettimeofday function is not used in this package. - This formerly let users obtain the current UTC offset and DST flag, - but this functionality was removed in later versions of BSD. - -* In SVR2, time conversion fails for near-minimum or near-maximum - time_t values when doing conversions for places that don't use UTC. - This package takes care to do these conversions correctly. - -The functions that are conditionally compiled if STD_INSPIRED is defined -should, at this point, be looked on primarily as food for thought. They are -not in any sense "standard compatible"--some are not, in fact, specified in -*any* standard. They do, however, represent responses of various authors to -standardization proposals. - -Other time conversion proposals, in particular the one developed by folks at -Hewlett Packard, offer a wider selection of functions that provide capabilities -beyond those provided here. The absence of such functions from this package -is not meant to discourage the development, standardization, or use of such -functions. Rather, their absence reflects the decision to make this package -contain valid extensions to POSIX, to ensure its broad acceptability. If -more powerful time conversion functions can be standardized, so much the -better. - - ------ Names of time zone rule files ----- - -The time zone rule file naming conventions attempt to strike a balance -among the following goals: - - * Uniquely identify every national region where clocks have all - agreed since 1970. This is essential for the intended use: static - clocks keeping local civil time. - - * Indicate to humans as to where that region is. This simplifes use. - - * Be robust in the presence of political changes. This reduces the - number of updates and backward-compatibility hacks. For example, - names of countries are ordinarily not used, to avoid - incompatibilities when countries change their name - (e.g. Zaire->Congo) or when locations change countries - (e.g. Hong Kong from UK colony to China). - - * Be portable to a wide variety of implementations. - This promotes use of the technology. - - * Use a consistent naming convention over the entire world. - This simplifies both use and maintenance. - -This naming convention is not intended for use by inexperienced users -to select TZ values by themselves (though they can of course examine -and reuse existing settings). Distributors should provide -documentation and/or a simple selection interface that explains the -names; see the 'tzselect' program supplied with this distribution for -one example. - -Names normally have the form AREA/LOCATION, where AREA is the name -of a continent or ocean, and LOCATION is the name of a specific -location within that region. North and South America share the same -area, `America'. Typical names are `Africa/Cairo', `America/New_York', -and `Pacific/Honolulu'. - -Here are the general rules used for choosing location names, -in decreasing order of importance: - - Use only valid POSIX file name components (i.e., the parts of - names other than `/'). Within a file name component, - use only ASCII letters, `.', `-' and `_'. Do not use - digits, as that might create an ambiguity with POSIX - TZ strings. A file name component must not exceed 14 - characters or start with `-'. E.g., prefer `Brunei' - to `Bandar_Seri_Begawan'. - Include at least one location per time zone rule set per country. - One such location is enough. Use ISO 3166 (see the file - iso3166.tab) to help decide whether something is a country. - However, uninhabited ISO 3166 regions like Bouvet Island - do not need locations, since local time is not defined there. - If all the clocks in a country's region have agreed since 1970, - don't bother to include more than one location - even if subregions' clocks disagreed before 1970. - Otherwise these tables would become annoyingly large. - If a name is ambiguous, use a less ambiguous alternative; - e.g. many cities are named San Jose and Georgetown, so - prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'. - Keep locations compact. Use cities or small islands, not countries - or regions, so that any future time zone changes do not split - locations into different time zones. E.g. prefer `Paris' - to `France', since France has had multiple time zones. - Use mainstream English spelling, e.g. prefer `Rome' to `Roma', and - prefer `Athens' to the true name (which uses Greek letters). - The POSIX file name restrictions encourage this rule. - Use the most populous among locations in a country's time zone, - e.g. prefer `Shanghai' to `Beijing'. Among locations with - similar populations, pick the best-known location, - e.g. prefer `Rome' to `Milan'. - Use the singular form, e.g. prefer `Canary' to `Canaries'. - Omit common suffixes like `_Islands' and `_City', unless that - would lead to ambiguity. E.g. prefer `Cayman' to - `Cayman_Islands' and `Guatemala' to `Guatemala_City', - but prefer `Mexico_City' to `Mexico' because the country - of Mexico has several time zones. - Use `_' to represent a space. - Omit `.' from abbreviations in names, e.g. prefer `St_Helena' - to `St._Helena'. - Do not change established names if they only marginally - violate the above rules. For example, don't change - the existing name `Rome' to `Milan' merely because - Milan's population has grown to be somewhat greater - than Rome's. - If a name is changed, put its old spelling in the `backward' file. - -The file `zone.tab' lists the geographical locations used to name -time zone rule files. It is intended to be an exhaustive list -of canonical names for geographic regions. - -Older versions of this package used a different naming scheme, -and these older names are still supported. -See the file `backward' for most of these older names -(e.g. `US/Eastern' instead of `America/New_York'). -The other old-fashioned names still supported are -`WET', `CET', `MET', `EET' (see the file `europe'), -and `Factory' (see the file `factory'). - - ------ Time zone abbreviations ----- - -When this package is installed, it generates time zone abbreviations -like `EST' to be compatible with human tradition and POSIX. -Here are the general rules used for choosing time zone abbreviations, -in decreasing order of importance: - - Use abbreviations that consist of three or more ASCII letters. - Previous editions of this database also used characters like - ' ' and '?', but these characters have a special meaning to - the shell and cause commands like - set `date` - to have unexpected effects. - Previous editions of this rule required upper-case letters, - but the Congressman who introduced Chamorro Standard Time - preferred "ChST", so the rule has been relaxed. - - This rule guarantees that all abbreviations could have - been specified by a POSIX TZ string. POSIX - requires at least three characters for an - abbreviation. POSIX through 2000 says that an abbreviation - cannot start with ':', and cannot contain ',', '-', - '+', NUL, or a digit. POSIX from 2001 on changes this - rule to say that an abbreviation can contain only '-', '+', - and alphanumeric characters from the portable character set - in the current locale. To be portable to both sets of - rules, an abbreviation must therefore use only ASCII - letters. - - Use abbreviations that are in common use among English-speakers, - e.g. `EST' for Eastern Standard Time in North America. - We assume that applications translate them to other languages - as part of the normal localization process; for example, - a French application might translate `EST' to `HNE'. - - For zones whose times are taken from a city's longitude, use the - traditional xMT notation, e.g. `PMT' for Paris Mean Time. - The only name like this in current use is `GMT'. - - If there is no common English abbreviation, abbreviate the English - translation of the usual phrase used by native speakers. - If this is not available or is a phrase mentioning the country - (e.g. ``Cape Verde Time''), then: - - When a country has a single or principal time zone region, - append `T' to the country's ISO code, e.g. `CVT' for - Cape Verde Time. For summer time append `ST'; - for double summer time append `DST'; etc. - When a country has multiple time zones, take the first three - letters of an English place name identifying each zone - and then append `T', `ST', etc. as before; - e.g. `VLAST' for VLAdivostok Summer Time. - - Use UTC (with time zone abbreviation "zzz") for locations while - uninhabited. The "zzz" mnemonic is that these locations are, - in some sense, asleep. - -Application writers should note that these abbreviations are ambiguous -in practice: e.g. `EST' has a different meaning in Australia than -it does in the United States. In new applications, it's often better -to use numeric UTC offsets like `-0500' instead of time zone -abbreviations like `EST'; this avoids the ambiguity. - - ------ Calendrical issues ----- - -Calendrical issues are a bit out of scope for a time zone database, -but they indicate the sort of problems that we would run into if we -extended the time zone database further into the past.

+# year. This year it will be observed September 13 (September is quite
+# hot in Egypt), and the idea is to make fasting easier for workers by
+# shifting business hours one hour out of daytime heat. Consequently,

+# I found there are some mistakes for the...DST rule for Hong
+# Kong. [According] to the DST record from Hong Kong Observatory (actually,
+# it is not [an] observatory, but the official meteorological agency of HK,
+# and also serves as the official timing agency), there are some missing
+# and incorrect rules. Although the exact switch over time is missing, I

+#
+# As I wrote in an earlier message, I suspected the current tzdata values
+# to be wrong. This is now verified.
+#
+# I have found copies of the original ruling by the Swiss Federal
+# government, in 'Eidgen[o]ssische Gesetzessammlung 1941 and 1942' (Swiss
+# federal law collection)...
+#
+# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
+# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
+#
+# DST began on Monday, 4 May 1942 at 01:00 am
+# DST ended on Monday, 5 Oct 1942 at 02:00 am
+#
+# There was no DST in 1940, I have checked the law collection carefully.
+# It is also indicated by the fact that the 1942 entry in the law
+# collection points back to 1941 as a reference, but no reference to any
+# other years are made.
+#
+# Newspaper articles I have read in the archives on 6 May 1941 reported
+# about the introduction of DST (Sommerzeit in German) during the previous
+# night as an absolute novelty, because this was the first time that such
+# a thing had happened in Switzerland.
+#
+# I have also checked 1916, because one book source (Gabriel, Traite de
+# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
+# false, no official document could be found. Probably Gabriel got misled
+# by references to Germany, which introduced DST in 1916 for the first time.
+#
+# The tzdata rules for Switzerland must be changed to:
+# Rule  Swiss   1941    1942    -       May     Mon>=1  1:00    1:00    S
+# Rule  Swiss   1941    1942    -       Oct     Mon>=1  2:00    0       -

+# 1980, Juneau and other nearby communities would move to Yukon Time.
+# Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on
+# Pacific Time.
+#
+# ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the
+# Department's September 1979 decision. Juneau and other communities in
+# northern Southeast reverted to Pacific Time on October 26.
+#
+# On October 28 [1983]...the Metlakatla Indian Community Council voted
+# unanimously to keep the reservation on Pacific Time.
+#
+# According to DOT official Joanne Petrie, Indian reservations are not
+# bound to follow time zones imposed by neighboring jurisdictions.
+#
+# (The last is consistent with how the database now handles the Navajo
+# Nation.)
+
+# From Arthur David Olson (2011-02-09):
+# I just spoke by phone with a staff member at the Metlakatla Indian
+# Community office (using contact information available at
+# 
+# http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla
+# ).
+# It's shortly after 1:00 here on the east coast of the United States;
+# the staffer said it was shortly after 10:00 there. When I asked whether
+# that meant they were on Pacific time, they said no--they were on their
+# own time. I asked about daylight saving; they said it wasn't used. I
+# did not inquire about practices in the past.
+
+# From Arthur David Olson (2011-08-17):
+# For lack of better information, assume that Metlakatla's
+# abandonment of use of daylight saving resulted from the 1983 vote.

-# From Chris Walton (2007-03-14):
-# Today I phoned the "hamlet office" to find out what Resolute was doing with
-# its clocks.
+# From Chris Walton (2011-03-21):
+# Back in 2007 I initiated the creation of a new "zone file" for Resolute
+# Bay. Resolute Bay is a small community located about 900km north of
+# the Arctic Circle. The zone file was required because Resolute Bay had
+# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007.
+#
+# According to new information which I received last week, Resolute Bay
+# went back to using UTC-6 in the winter of 2007-2008...
+#
+# On March 11/2007 most of Canada went onto daylight saving. On March
+# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
+# talked to somebody that was both knowledgeable and helpful. I was able
+# to confirm that Resolute Bay was still operating on UTC-5. It was
+# explained to me that Resolute Bay had been on the Eastern Time zone
+# (EST) in the winter, and was now back on the Central Time zone (CDT).
+# i.e. the time zone had changed twice in the last year but the clocks
+# had not moved. The residents had to know which time zone they were in
+# so they could follow the correct TV schedule...
+#
+# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
+# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
+# of the phone call, I decided to seek out an alternate source of
+# information. I found an e-mail address for somebody by the name of
+# Stephanie Adams whose job was listed as "Inns North Support Officer for
+# Arctic Co-operatives." I was under the impression that Stephanie lived
+# and worked in Resolute Bay...
+#
+# On March 14/2011 I phoned the hamlet office again. I was told that
+# Resolute Bay had been using Central Standard Time over the winter of
+# 2010-2011 and that the clocks had therefore been moved one hour ahead
+# on March 13/2011. The person I talked to was aware that Resolute Bay
+# had previously experimented with Eastern Standard Time but he could not
+# tell me when the practice had stopped.
+#
+# On March 17/2011 I searched the Web to find an e-mail address of
+# somebody that might be able to tell me exactly when Resolute Bay went
+# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz
+# used to be the mayor of Resolute Bay and he apparently owns half the
+# businesses including "South Camp Inn." This website has some info on
+# Aziz:
+# 
+# http://www.uphere.ca/node/493
+# 
+#
+# I sent Aziz an e-mail asking when Resolute Bay had stopped using
+# Eastern Standard Time.
 #
-# The individual that answered the phone confirmed that the clocks did not
-# move at the end of daylight saving on October 29/2006.  He also told me that
-# the clocks did not move this past weekend (March 11/2007)....
+# Aziz responded quickly with this: "hi, The time was not changed for the
+# 1 year only, the following year, the community went back to the old way
+# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in
+# the winter Zulu plus 6 hrs"
 #
-# America/Resolute should use the "Canada" Rule up to October 29/2006.
-# After that it should be fixed on Eastern Standard Time until further notice.
+# This of course conflicted with everything I had ascertained in November 2008.
+#
+# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz
+# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You
+# may want to check with the weather office in Resolute Bay or do a
+# search on the weather through Env. Canada. web site"
+#
+# If I had realized the Stephanie did not live in Resolute Bay I would
+# never have contacted her.  I now believe that all the information I
+# obtained in November 2008 should be ignored...
+# I apologize for reporting incorrect information in 2008.

+# 
+# confirms what Alex Krivenyshev has earlier sent to the tz

+# confirms that upon request the provinces San Juan and Mendoza 
+# refused to follow San Luis in this change. 
+# 
+# The change is supposed to take place Monday the 21.st at 0:00
+# hours. As far as I understand it if this goes ahead, we need

+# 1 hour), and they intend to keep UTC-3 as their timezone all year round
+# (that is, unless they change their mind any minute now).
+#
+# So we'll have to add yet another city to 'southamerica' (I think San

+# From Mariano Absatz (2009-03-13):

+# 
+# (I couldn't find the decree, but

+# There's also a note in only one of the major national papers (La Nación) at
+# 
+# http://www.lanacion.com.ar/nota.asp?nota_id=1107912
+# 
+# 
+# The press release says:

+#
+# A partir de entonces, San Luis establecerá el huso horario propio de

+# Quick&dirty translation
+# (...) announced that next Sunday, at 00:00, Puntanos (the San Luis
+# inhabitants) will have to turn back one hour their clocks
+#
+# Since then, San Luis will establish its own Province timezone. Thus,
+# during 2009, this timezone change will run from 00:00 the third Sunday
+# in March until 24:00 of the second Saturday in October.
+
+# From Mariano Absatz (2009-10-16):
+# ...the Province of San Luis is a case in itself.
 #
+# The Law at
+# 
+# is ambiguous because establishes a calendar from the 2nd Sunday in
+# October at 0:00 thru the 2nd Saturday in March at 24:00 and the
+# complement of that starting on the 2nd Sunday of March at 0:00 and
+# ending on the 2nd Saturday of March at 24:00.
+#
+# This clearly breaks every time the 1st of March or October is a Sunday.
+#
+# IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
+# Sunday of October and March.
+#
+# The problem is that the changes in the rest of the Provinces that did
+# change in 2007/2008, were made according to the Federal Law and Decrees
+# that did so on the 3rd Sunday of October and March.
+#
+# In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
+# (October 11th) at 0:00.
+#
+# So I guess a new set of rules, besides "Arg", must be made and the last
+# America/Argentina/San_Luis entries should change to use these...
+#
+# I'm enclosing a patch that does what I say... regretfully, the San Luis
+# timezone must be called "WART/WARST" even when most of the time (like,
+# right now) WARST == ART... that is, since last Sunday, all the country
+# is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
+# of the country calls it "ART".
+# ...
+
+# From Alexander Krivenyshev (2010-04-09):
+# According to news reports from El Diario de la Republica Province San
+# Luis, Argentina (standard time UTC-04) will keep Daylight Saving Time

+# From Paul Schulze (2008-06-24):
+# ...by law number 11.662 of April 24, 2008 (published in the "Diario
+# Oficial da Uniao"...) in Brazil there are changes in the timezones,
+# effective today (00:00am at June 24, 2008) as follows:
+#
+# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
+# part of the Amazonas state that had this timezone now being put to the
+# timezone UTC+4
+# b) The whole Para state now is put at timezone UTC+3, instead of just
+# part of it, as was before.
+#
+# This change follows a proposal of senator Tiao Viana of Acre state, that
+# proposed it due to concerns about open television channels displaying
+# programs inappropriate to youths in the states that had the timezone
+# UTC+5 too early in the night. In the occasion, some more corrections
+# were proposed, trying to unify the timezones of any given state. This
+# change modifies timezone rules defined in decree 2.784 of 18 June,
+# 1913.
+
+# From Rodrigo Severo (2008-06-24):
+# Just correcting the URL:
+# 
+# https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008
+# 
+#
+# As a result of the above Decree I believe the America/Rio_Branco
+# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
+# be created to represent the...west side of the Para State. I
+# suggest this new timezone be called Santarem as the most
+# important/populated city in the affected area.
+#
+# This new timezone would be the same as the Rio_Branco timezone up to
+# the 2008/06/24 change which would be to UTC-3 instead of UTC-4.
+
+# From Alex Krivenyshev (2008-06-24):
+# This is a quick reference page for New and Old Brazil Time Zones map.
+# 
+# http://www.worldtimezone.com/brazil-time-new-old.php
+# 
+#
+# - 4 time zones replaced by 3 time zones-eliminating time zone UTC- 05
+# (state Acre and the part of the Amazonas will be UTC/GMT- 04) - western
+# part of Par state is moving to one timezone UTC- 03 (from UTC -04).

-time zone mailing list.

-
The tz database

-

-The public-domain time zone database contains code and data
-that represent the history of local time
-for many representative locations around the globe.
-It is updated periodically to reflect changes made by political bodies
-to time zone
-boundaries, UTC offsets, and
-daylight-saving
-rules.
-This database (often called tz or zoneinfo)
-is used by several implementations,
-including
-the
-GNU
-C Library used in
-GNU/Linux,
-FreeBSD,
-NetBSD,
-OpenBSD,
-Cygwin,
-DJGPP,
-HP-UX,
-IRIX,
-Mac OS X,
-OpenVMS,
-Solaris,
-Tru64, and
-UnixWare.

-

-Each location in the database represents a national region where all
-clocks keeping local time have agreed since 1970.
-Locations are identified by continent or ocean and then by the name of
-the location, which is typically the largest city within the region.
-For example, America/New_York
-represents most of the US eastern time zone;
-America/Phoenix represents most of Arizona, which
-uses mountain time without daylight saving time (DST);
-America/Detroit represents most of Michigan, which uses
-eastern time but with different DST rules in 1975;
-and other entries represent smaller regions like Starke County,
-Indiana, which switched from central to eastern time in 1991
-and switched back in 2006.
-To use the database on an extended POSIX
-implementation set the TZ environment variable to
-the location's full name, e.g., TZ="America/New_York".

-

-In the tz database's
-FTP distribution
-the code is in the file tzcodeC.tar.gz,
-where C is the code's version;
-similarly, the data are in tzdataD.tar.gz,
-where D is the data's version.
-The following shell commands download
-these files to a GNU/Linux or similar host;
-see the downloaded
-README file for what to do next.

-
wget 'ftp://elsie.nci.nih.gov/pub/tz*.tar.gz'
-gzip -dc tzcode*.tar.gz | tar -xf -
-gzip -dc tzdata*.tar.gz | tar -xf -
-

-

-The code lets you compile the tz source files into
-machine-readable binary files, one for each location. It also lets
-you read a tz binary file and interpret time stamps for that
-location.

-

-The data are by no means authoritative. If you find errors, please
-send changes to the time zone
-mailing list. You can also subscribe to the
-mailing list, retrieve the archive of old
-messages (in gzip compressed format), or retrieve archived older versions of code
-and data; there is also a smaller HTTP
-mirror.

-

-The Web has several other sources for time zone and daylight saving time data.
-Here are some recent links that may be of interest.

  • 
-A Summary of
-the International Standard Date and Time Notation is a good
-summary of
-ISO
-8601:2004 -- Data elements and interchange formats -- Information
-interchange -- Representation of dates and times.
    • 
-
  • 
-XML
-Schema: Datatypes - dateTime specifies a format inspired by
-ISO 8601 that is in common use in XML data.
    •

-specifies the time notation used in email and HTTP
-headers.
    • 
-

-profile for use in new Internet

-formats.
    • 
-
  • 
-The
-Best of Dates, the Worst of Dates covers many problems encountered
-by software developers when handling dates and time stamps.
    • 
-
  • ICU
-contains a mechanism for localizing time zone
-labels and abbreviations; for example, one can use it to specify
-Russian translations for "Eastern European Summer Time",
-"EEST",
-and Europe/Bucharest.
-This mechanism is part of the
-Unicode
-CLDR Project;
-for example, the CLDR Sideways Data for dates_timeZoneNames
-shows values for time zone names in many locales.
    • 
-
  • Alphabetic time zone abbreviations should not be used as unique
-identifiers for UTC offsets as they are ambiguous in
-practice. For example, "EST" denotes 5 hours behind
-UTC in English-speaking North America, but it denotes 10
-or 11 hours ahead of UTC in Australia; and
-French-speaking North Americans prefer
-"HNE" to
-"EST". For POSIX the tz
-database contains English abbreviations for all time stamps but in
-many cases these are merely inventions of the database
-maintainers.
    • 
-
  • Numeric time zone abbreviations typically count hours east of
-UTC, e.g., +09 for Japan and
--10 for Hawaii. However, the POSIX
-TZ environment variable uses the opposite convention. For
-example, one might use TZ="JST-9" and
-TZ="HST10" for Japan and Hawaii, respectively. If the
-tz database is available, it is usually better to use
-settings like TZ="Asia/Tokyo" and
-TZ="Pacific/Honolulu" instead, as this should avoid
-confusion, handle old time stamps better, and insulate you better from
-any future changes to the rules. One should never set
-POSIX TZ to a value like
-"GMT-9", though, since this would falsely claim that
-local time is nine hours ahead of UTC and the time zone
-is called "GMT".
