Did you read the documentation or try it?  Perhaps you're thinking
of now(), current_timestamp, and friends, which don't advance during
a transaction; but as the documentation states, "timeofday() returns
the wall-clock time and does advance during transactions."

I just ran tests on versions of PostgreSQL going back to 7.2.8 and
in all of them timeofday() advanced during a transaction.  Does it
not work on your system?  If not then something's broken -- what
OS and version of PostgreSQL are you using?
