DateTime::TimeZone::Local::Win32(3) User Contributed Perl Documentation DateTime::TimeZone::Local::Win32(3) NAME
DateTime::TimeZone::Local::Win32 - Determine the local system's time zone on Windows VERSION
version 1.63 SYNOPSIS
my $tz = DateTime::TimeZone->new( name => 'local' ); my $tz = DateTime::TimeZone::Local->TimeZone(); DESCRIPTION
This module provides methods for determining the local time zone on a Windows platform. HOW THE TIME ZONE IS DETERMINED
This class tries the following methods of determining the local time zone: o $ENV{TZ} It checks $ENV{TZ} for a valid time zone name. o Windows Registry When using the registry, we look for the Windows time zone and use a mapping to translate this to an Olson time zone name. o Windows Vista and 2008 We look in "SYSTEM/CurrentControlSet/Control/TimeZoneInformation/" for a node named "/TimeZoneKeyName". If this exists, we use this key to look up the Olson time zone name in our mapping. o Windows NT, Windows 2000, Windows XP, Windows 2003 Server We look in "SOFTWARE/Microsoft/Windows NT/CurrentVersion/Time Zones/" and loop through all of its sub keys. For each sub key, we compare the value of the key with "/Std" appended to the end to the value of "SYSTEM/CurrentControlSet/Control/TimeZoneInformation/StandardName". This gives us the English name of the Windows time zone, which we use to look up the Olson time zone name. o Windows 95, Windows 98, Windows Millenium Edition The algorithm is the same as for NT, but we loop through the sub keys of "SOFTWARE/Microsoft/Windows/CurrentVersion/Time Zones/" AUTHOR
