Dmitriy V. Ryaboy commented on PIG-1310:
----------------------------------------
It builds -- you just have to build pig with the test classes first, *then*
test piggybank. Those Piggybank tests require some of the test helpers Pig has.

> 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.
