Thejas M Nair commented on PIG-1314:
------------------------------------
bq. One quick issue: we need to give a name to the new type. We are supposed to
use "DATETIME", correct? Or "DATE", "TIMESTAMP"?
"datetime" makes sense when it has both date and time (hrs,mins,secs) parts to
it. The problem with using (unix) timestamp, is that the date range is limited
to 78 years. Using jodatime, we will be able to support much larger date range
than timestamp.

> 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?
> This is a candidate project for Google summer of code 2012. More information
