=head1 NAME
Date.W3CDTF - W3C Date and Time Formats
=head1 SYNOPSIS
var dd = new Date.W3CDTF(); // now
document.write( "getW3CDTF: "+ dd.getW3CDTF() +"ý_n" );
dd.setW3CDTF( "2005-04-23T17:20:00+09:00" );
document.write( "toLocaleString: "+ dd.toLocaleString() +"ý_n" );
=head1 DESCRIPTION
This module understands the W3CDTF date/time format, an ISO 8601 profile,
defined by W3C. This format as the native date format of RSS 1.0.
It can be used to parse these formats in order to create the appropriate objects.
=head1 METHODS
=head2 new()
This constructor method creates a new Date object which has
following methods in addition to Date's all native methods.
=head2 setW3CDTF( "2006-02-15T19:40:00Z" )
This method parse a W3CDTF datetime string and sets it.
=head2 getW3CDTF()
This method returns a W3CDTF datetime string.
Its timezone is always local timezone configured on OS.
