I don't see how storing the time in seconds helps. Once you do that you
can't use the to_date functions to format the output. I also don't see
gaining much in terms of speed either. Timestamps are wider than ints,
but are going to be fast to work with.

While looking for ideas about this I noticed a lack of to_date functions for
printing intervals. I think it would be nice to be able to do something like
the following:
select to_char(now() - 'epoch', 'SSSSSSSSSSSSS');
and get the result:
979333398
