Subject [jira] Updated: (PIG-1310) ISO Date UDFs: Conversion, Trucation and Date Math
Date Mon, 29 Mar 2010 19:52:30 GMT

     [ https://issues.apache.org/jira/browse/PIG-1310?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Russell Jurney updated PIG-1310:
--------------------------------

    Attachment: combined.patch

All inclusive patch from pig root, includes all classes and tests, and ivy updates for jodatime.
 Applied this to a fresh trunk svn checkout, and all works ok - once I remove failing tests
in piggybank unrelated to this commit.

> I've written UDFs to handle loading unix times, datemonth values and ISO 8601 formatted
date strings, and working with them as ISO datetimes using jodatime.
> The working code is here: http://github.com/rjurney/oink/tree/master/src/java/oink/udf/isodate/
> It needs to be documented and tests added, and a couple UDFs are missing, but these work
if you REGISTER the jodatime jar in your script.  Hopefully I can get this stuff in piggybank
before someone else writes it this time :)  The rounding also may not be performant, but the
code works.
> Ultimately I'd also like to enable support for ISO 8601 durations.  Someone slap me if
this isn't done soon, it is not much work and this should help everyone working with time
series.
