Time::Zone(3) User Contributed Perl Documentation Time::Zone(3) 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 AUTHORS Graham Barr David Muir Sharnoff Paul Foley perl v5.38.0 2023-07-25 Time::Zone(3)
