Time::Timezone(3)

NAME
Time::Timezone -- miscellaneous timezone manipulations routines

SYNOPSIS
        use Time::Timezone;
        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-like output. It optionally takes a timezone string, a time, and a is-dst flag.

"tz_local_offset()" determines 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
