+In this case, the real and effective IDs are assumed to be the same.

+If the effective user ID is different from the real user ID, the real user
+ID is displayed as a name, preceded by the keyword ``euid''.
+If the effective group ID is different from the real group ID, the real group
+ID is displayed as a name, preceded by the keyword ``rgid''.
+The list of groups to which the user belongs is then displayed as names,

+.It Ar CC
+The first two digits of the year (the century).

+The second two digits of the year.
+If
+.Dq YY

+utility is compliant with the
+.St -p1003.1-2004
+specification.
+.Pp
+The obsolescent form of
+.Nm touch ,
+where a time format is specified as the first argument, is supported.
+When no
+.Fl r
+or
+.Fl t
+option is specified, there are at least two arguments, and the first
+argument is a string of digits either eight or ten characters in length,
+the first argument is interpreted as a time specification of the form
+.Dq MMDDhhmm[YY] .
+.Pp
+The
+.Dq MM ,
+.Dq DD ,
+.Dq hh
+and
+.Dq mm
+letter pairs are treated as their counterparts specified to the
+.Fl t
+option.
+If the
+.Dq YY
+letter pair is in the range 69 to 99, the year is set from 1969 to 1999;
+otherwise, the year is set in the 21st century.
