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".

  If this exists, we use its values to determine the currently selected time zone key from the registry. The name of this key is the 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.
