Date Diff

Greetings all,

     A while ago I was using asp and when I started using php the harder thing to learn was "Dealing with dates". There isn't a datediff function like asp.. Instead you have timestamps. Powerful it may be but a little hard to learn about and use. Other wise I find php to be very nice and simple as well powerful.

So what happens if you have two timestamps and you want to find out what the difference is? There has to be some function that I don't know about.. I have to be missing somethig! Adam
