Time::Zone -- miscellaneous timezone manipulations routines

SYNOPSIS

use Time::Zone;
print tz2zone();

DESCRIPTION

This is a collection of miscellaneous timezone manipulation routines.

tz2zone() parses the TZ environment variable and returns a timezone string suitable for inclusion in date(1)-like output. It opionally takes a timezone string, a time, and a is-dst flag.

tz_local_offset() determins the offset from GMT time in seconds. It only does the calculation once.

tz_offset() determines the offset from GMT in seconds of a specified timezone.

tz_name() determines the name of the timezone based on its offset
