If you want to produce a time_t painlessly, the simplest way is not
to SELECT the raw timestamp, but rather date_part('epoch', timestamp).
This gives you back an integer number of seconds per Unix conventions,
which you just use atoi() on.  For example:

regression=# select date_part('epoch', now());
 date_part
