DateTime::TimeZone::SystemV 0.000

DateTime::TimeZone::SystemV is a Perl module with System V and POSIX timezone strings.

SYNOPSIS

use DateTime::TimeZone::SystemV;

$tz = DateTime::TimeZone::SystemV->new("EST5EDT");

if($tz->is_floating) { ...
if($tz->is_utc) { ...
if($tz->is_olson) { ...
$category = $tz->category;
$tz_string = $tz->name;

if($tz->has_dst_changes) { ...
if($tz->is_dst_for_datetime($dt)) { ...
$offset = $tz->offset_for_datetime($dt);
$abbrev = $tz->short_name_for_datetime($dt);
$offset = $tz->offset_for_local_datetime($dt);

An instance of this class represents a timezone that was specified by means of a System V timezone string or the POSIX extended form of the same syntax. These can express a plain offset from Universal Time, or a system of two offsets (standard and daylight saving time) switching on a yearly cycle according to certain types of rule.

This class implements the DateTime::TimeZone interface, so that its instances can be used with DateTime objects.
