1 This distribution implement detection of the local timezone as defined at
2 the operating system level, either in $ENV{TZ} or in /etc/TIMEZONE.
4 HP-UX has its own system for defining timezones. See tztab(4). This is
5 incompatible with the now common set of timezones known as the Olson DB
6 that is used by DateTime::TimeZone. This module fixes this hole by
7 providing the map between the two systems.
