I've read through all the documentation, and I can't find a function that takes a timestamp and converts iit to seconds since epoch. Here's what I need to do: I have pairs of timestamps ('2000-07-12 03:33:53+00'), and I want to find out how many seconds are in the interval between them. I know I can do select timestamp1 - timestamp2 and I get a result in days, hours, mins, and seconds, but is there a way to get that whole thing in just seconds? This has to be pretty efficient, because it's going to get called a lot. Thanks, e
