Cheolsoo Park commented on PIG-3587:
------------------------------------

[~rekhajoshm], thank you very much for the patch.

The functionality seems very similar to [AddDuration|http://pig.apache.org/docs/r0.12.0/func.html#add-duration] and [SubtractDuration|http://pig.apache.org/docs/r0.12.0/func.html#subtract-duration]. For example, to add 1 month, I can do the following-
{code}
t = FOREACH s GENERATE AddDuration( ToDate(str, 'yyyy-MM-dd'), 'P1M' );
{code}
I am not sure whether we want to add another UDF for this. What do you think?
