Description

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 about the program can be found at https://cwiki.apache.org/confluence/display/PIG/GSoc2012
