libdatetime-format-iso8601-perl 0.06-2 (powerpc binary) in ubuntu precise

 DateTime::Format::ISO8601 parses almost all ISO8601 date and time formats.
 .
 The signature feature of ISO 8601 date and time representations is the
 ordering of date and time values from the most to the least significant or,
 in plain terms, from the largest (the year) to the smallest (the second).
 .
   Example date: 2008-04-18
   Example separate date and time in UTC: 2008-04-18 08:47Z
   Example combined date and time in UTC: 2008-04-18T08:47Z
   Example date with week number: 2008-W16-5
 .
 ISO8601 time-intervals will be supported in a later release.
