NAME
    Time::Zone -- miscellaneous timezone manipulations routines

SYNOPSIS
            use Time::Zone;
            print tz2zone();
            print tz2zone($ENV{'TZ'});
            print tz2zone($ENV{'TZ'}, time());
            print tz2zone($ENV{'TZ'}, undef, $isdst);
            $offset = tz_local_offset();
            $offset = tz_offset($TZ);

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
