NAME

DateTime::TimeZone::Local::Win32 - Determine the local system's time zone on Windows

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:

• $ENV{TZ}

  It checks $ENV{TZ} for a valid time zone name.

• Windows Registry

  We check for a registry key called "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\StandardName".

  If this exists, it contains a Windows name for the time zone. We use a lookup table to translate this into an equivalent time zone name.

  This lookup table was borrowed from the Chronos Smalltalk library.
