Thread: Rounding datetimes
Is there a way to round an interval to the nearest minute or do I need to create a function for this?

TIP 5: don't forget to increase your free space map settings
date_trunc('minute',interval)

If you want to round up/down to the nearest minute I suppose you could just add '30 seconds'::interval before truncating. select now(), date_trunc('minute', now()), date_trunc('minute', now()+'30 seconds'::interval); -[ RECORD 1 ]----------------------------- now | 2007-05-22 10:25:37.706279-07 date_trunc | 2007-05-22 10:25:00-07 date_trunc | 2007-05-22 10:26:00-07 Cheers, Steve
