Keuntae Park commented on TAJO-448:
-----------------------------------

It looks good to me, too.
But, are 32 bits enough to represent unix time?
32 bits unix time only supports up to 2038-01-19 and PostgreSQL looks to 
support bigger than 32 bits unix time.

> Timestamp should be based on unixtime
