NAME

       MooseX::Types::DateTime - DateTime related constraints and coercions for Moose

VERSION

       version 0.10

SYNOPSIS

       Export Example:

	   use MooseX::Types::DateTime qw(TimeZone);

	   has time_zone => (
	       isa => TimeZone,
	       is => "rw",
	       coerce => 1,
	   );

	   Class->new( time_zone => "Africa/Timbuktu" );

       Namespaced Example:

	   use MooseX::Types::DateTime;

	   has time_zone => (
	       isa => 'DateTime::TimeZone',
	       is => "rw",
	       coerce => 1,
	   );

	   Class->new( time_zone => "Africa/Timbuktu" );

DESCRIPTION

       This module packages several Moose::Util::TypeConstraints with coercions, designed to work with the DateTime suite of objects.

CONSTRAINTS

       DateTime
	   A class type for DateTime.

	   from "Num"
	       Uses "from_epoch" in DateTime. Floating values will be used for sub-second precision, see DateTime for details.

	   from "HashRef"
	       Calls "new" in DateTime with the hash entries as arguments.

       Duration
	   A class type for DateTime::Duration

	   from "Num"
	       Uses "new" in DateTime::Duration and passes the number as the "seconds" argument.

	       Note that due to leap seconds, DST changes etc this may not do what you expect.	For instance passing in 86400 is not always
	       equivalent to one day, although there are that many seconds in a day. See "How Date Math is Done" in DateTime for more details.

	   from "HashRef"
	       Calls "new" in DateTime::Duration with the hash entries as arguments.

       DateTime::Locale
	   A class type for DateTime::Locale::root with the name DateTime::Locale.

	   from "Str"
	       The string is treated as a language tag (e.g. "en" or "he_IL") and given to "load" in DateTime::Locale.

	   from Locale::Maktext
	       The "Locale::Maketext/language_tag" attribute will be used with "load" in DateTime::Locale.

	   DateTime::TimeZone
	       A class type for DateTime::TimeZone.

	       from "Str"
		   Treated as a time zone name or offset. See "USAGE" in DateTime::TimeZone for more details on the allowed values.

		   Delegates to "new" in DateTime::TimeZone with the string as the "name" argument.

NAME

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

VERSION

       version 1.51

SYNOPSIS

	 my $tz = DateTime::TimeZone->new( name => 'local' );

	 my $tz = DateTime::TimeZone::Local->TimeZone();

DESCRIPTION

       This module provides an interface for determining the local system's time zone. Most of the functionality for doing this is in OS-specific
       subclasses.

USAGE

       This class provides the following methods:

   DateTime::TimeZone::Local->TimeZone()
       This attempts to load an appropriate subclass and asks it to find the local time zone. This method is called by when you pass "local" as
       the time zone name to "DateTime:TimeZone->new()".

       If your OS is not explicitly handled, you can create a module with a name of the form "DateTime::TimeZone::Local::$^O". If it exists, it
       will be used instead of falling back to the Unix subclass.

       If no OS-specific module exists, we fall back to using the Unix subclass.

       See DateTime::TimeZone::Local::Unix, DateTime::TimeZone::Local::Win32, and DateTime::TimeZone::Local::VMS for OS-specific details.

SUBCLASSING

       If you want to make a new OS-specific subclass, there are several methods provided by this module you should know about.

   $class->Methods()
       This method should be provided by your class. It should provide a list of methods that will be called to try to determine the local time
       zone.

       Each of these methods is expected to return a new "DateTime::TimeZone" object if it determines the time zone.

   $class->FromEnv()
       This method tries to find a valid time zone in an %ENV value. It calls "$class->EnvVars()" to determine which keys to look at.

       To use this from a subclass, simply return "FromEnv" as one of the items from "$class->Methods()".

   $class->EnvVars()
       This method should be provided by your subclass. It should return a list of env vars to be checked by "$class->FromEnv()".

   $class->_IsValidName($name)
       Given a possible time zone name, this returns a boolean indicating whether or not the the name looks valid. It always return false for
       "local" in order to avoid infinite loops.

EXAMPLE SUBCLASS

       Here is a simple example subclass:

	 package DateTime::TimeZone::SomeOS;

	 use strict;
	 use warnings;

	 use base 'DateTime::TimeZone::Local';

	 sub Methods { qw( FromEnv FromEther ) }

	 sub EnvVars { qw( TZ ZONE ) }

	 sub FromEther
	 {
	     my $class = shift;

	     ...
	 }
