Alan Gates commented on PIG-1310:
---------------------------------
New patch looks good. Piggybank tests pass. I'm rerunning the patch test to
check things like javac warnings, etc. As long as that all returns success
I'll commit it. Then I'll apply it to 0.7, test it there, and assuming all is
well, commit it there too.

> 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.
