.SH NAME
DateTime::Format::W3CDTF \- Parse and format W3CDTF datetime strings
.SH VERSION
.IX Header "VERSION"
This document describes DateTime::Format::W3CDTF version 0.09
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\&  use DateTime::Format::W3CDTF;
\&
\&  my $w3c = DateTime::Format::W3CDTF\->new(strict => 1);
\&  my $dt = $w3c\->parse_datetime( \*(Aq2003\-02\-15T13:50:05\-05:00\*(Aq );

.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module understands the W3CDTF date/time format, an ISO 8601 profile,
defined at http://www.w3.org/TR/NOTE\-datetime.  This format as the native
date format of RSS 1.0.
.PP
It can be used to parse these formats in order to create the appropriate 
objects.
.SH METHODS
.IX Header "METHODS"
This API is currently experimental and may change in the future.
.IP \(bu 4
\&\fBnew()\fR
.Sp
Returns a new W3CDTF parser object.  Accepts a single \f(CW\*(C`strict\*(C'\fR option:
.Sp
.Vb 1
\&  DateTime::Format::W3CDTF\->new(strict => 1);
.Ve
.Sp
If true, \fBparse_datetime()\fR and \fBformat_datetime()\fR will only accept and
return strings in W3CDTF format, respectively.  In particular, the
W3CDTF format requires all time components to have timezones.
.Sp
If false, timezones are optional.
.IP \(bu 4
parse_datetime($string)
.Sp
Given a W3CDTF datetime string, this method will return a new
\&\f(CW\*(C`DateTime\*(C'\fR object.
.Sp
If given an improperly formatted string, this method may die.
.IP \(bu 4
format_datetime($datetime)
.Sp
Given a \f(CW\*(C`DateTime\*(C'\fR object, this methods returns a W3CDTF datetime
string.
.Sp
NOTE: As of version 0.4, format_datetime no longer attempts to truncate
datetimes without a time component.  This is due to the fact that \f(CW\*(C`DateTime\*(C'\fR
doesn\*(Aqt distinguish between a date with no time component, and midnight.
.IP \(bu 4
format_date($datetime)
.Sp
Given a \f(CW\*(C`DateTime\*(C'\fR object, return a W3CDTF datetime string without the time component.
