Maybe I'm just overlooking something really simple but this has me a bit confused. What I'm trying to do is get the amount of time from A to B -- I thought age() would do just that but it seems to be about a day off sometimes. hhs=# SELECT age('Sun Dec 03 08:00:00 2000 EST','Tue Oct 10 08:00:00 2000 EDT') as esec; esec ------------------------ @ 1 mon 24 days 1 hour (1 row) Ok, but if I turn right around and add that value back , I get : hhs=# SELECT ('Tue Oct 10 08:00:00 2000 EDT'::timestamp + '1 mon 24 days 1 hour'::interval); ?column? ------------------------------ Mon Dec 04 08:00:00 2000 EST (1 row) Like I said, perhaps I'm blind and can't see what's happening here but shouldn't that be Sunday the 3rd of December? Thanks! -Mitch
