Hi Vincent,

We had a discussion on this very issue on this mailing list last week. 
If you go to
http://www.postgresql.org/mhonarc/pgsql-interfaces/2000-06/threads.html
and search the page for "Timestamps" you'll see the thread.  The first
message in the thread includes a patch that's been working for me.

HTH

Regards,
Jim
