Russell Jurney commented on PIG-1314:
-------------------------------------
Jodatime seems to solve these problems. Serializing from a string without a
timezone, it does things in a reasonable manner. Serializing things from a
string with a timezone, it does things in a reasonable manner.
Are we discussing a user-facing API, or an internal storage mechanism? I'm not
clear on which. Regarding the interface, presenting integers to a user as an
interface seems wrong to me. Excluding certain timezones in the name of
efficiency also seems wrong to me. The point of a datetime type is to add
timezones, otherwise we can simply use longs.
As an internal storage mechanism, I'm un-opinionated, so long as all timezones
are retained at all times.

> Hadoop/Pig are primarily used to parse log data, and most logs have a
> timestamp component. Therefore Pig should support dates as a primitive.
> Can someone familiar with adding types to pig comment on how hard this is?
> We're looking at doing this, rather than use UDFs. Is this a patch that
> would be accepted?
