DateTime::Format::W3CDTF(3) Parse and format W3CDTF datetime strings


use DateTime::Format::W3CDTF;
my $w3c = DateTime::Format::W3CDTF->new;
my $dt = $w3c->parse_datetime( '2003-02-15T13:50:05-05:00' );
# 2003-02-15T13:50:05-05:00


This module understands the W3CDTF date/time format, an ISO 8601 profile, defined at 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.


This API is currently experimental and may change in the future.
  • new()

    Returns a new W3CDTF parser object.

  • parse_datetime($string)

    Given a W3CDTF datetime string, this method will return a new "DateTime" object.

    If given an improperly formatted string, this method may die.

  • format_datetime($datetime)

    Given a "DateTime" object, this methods returns a W3CDTF datetime string.

    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 "DateTime" doesn't distinguish between a date with no time component, and midnight.

  • format_date($datetime)

    Given a "DateTime" object, return a W3CDTF datetime string without the time component.
