=head1 NAME

MooseX::Types::DateTime::MoreCoercions - Extensions to L<MooseX::Types::DateTime>

=head1 SYNOPSIS

    package MyApp::MyClass;

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

    has created => (
        isa => DateTime,
        is => "rw",
        coerce => 1,
    );

    my $instance = MyApp::MyClass->new(created=>'January 1, 1980');
    print $instance->created->year; # is 1980

    ## Coercions from the base type continue to work as normal.
    my $instance = MyApp::MyClass->new(created=>{year=>2000,month=>1,day=>10});

Please see the test case for more example usage.

=head1 DESCRIPTION

This module builds on L<MooseX::Types::DateTime> to add additional custom types and coercions.  Since it builds on an existing type, all coercions and constraints are inherited.

=head1 SUBTYPES

This module defines the following additional subtypes.

=head2 DateTime

Subtype of L<MooseX::Types::DateTime/DateTime>.  Adds an additional coercion from strings.

Uses L<DateTimeX::Easy> to try and convert strings, like "yesterday" into a valid L<DateTime> object.  Please note that due to ambiguity with how different systems might localize their timezone, string parsing may not always return the most expected value.  IN general we try to localize to UTC whenever possible.  Feedback welcomed!

=head2 Duration

Subtype of L<MooseX::Types::DateTime/Duration> that coerces from a string.  We use the module L<Time::Duration::Parse> to attempt this.

=head1 CAVEATS

Firstly, this module uses L<DateTimeX::Easy> which is way more DWIM than any sane person would desire. L<DateTimeX::Easy> works by falling back until something makes sense, this is variable. Furthermore, all the modules that L<DateTimeX::Easy> *can* use aren't required for "proper" function of L<DateTimeX::Easy>. What does this mean? Simple, your mileage may vary in your coercions because L<DateTimeX::Easy> is installation specific.
