Amit Chauhan commented on HIVE-19370:
-------------------------------------
[~bharos92] I think this should be fine,
IMO if string [correct]value is provided user should cast it as timestamp and
the Default TS format and provide as input for adding months.
for TS format you can document that udf expects in default TS format and that
should be sufficient.
Thanks for taking this up.
