DateTime::Format::W3CDTF - Parse and format W3CDTF datetime strings


  use DateTime::Format::W3CDTF;

  my $f = DateTime::Format::W3CDTF->new;
  my $dt = $f->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.

  • 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.


Support for this module is provided via the email list. See for more details.
