SPUG: Portable way to get local time zone

[John Labovitz]

Try the "POSIX" module's tzset() and tzname() subroutines.  (Type "man
POSIX" and search for "tzname".)  These are identical to the C library
routines, and most Unixes use the same base timezone information & library
(from NIH).

The tzset() subroutine initializes the program to the timezone as specified
in $ENV{TZ}, or whatever is the default on the system.  The tzname()
subroutine returns a list of two "short"-style timezone names.  Note that
these short names can be ambiguous -- for instance, "EST" stands for
timezones in both eastern Australia and the eastern US.
