I noticed there is no function in php to tell the duration between two times, unless of course there is and i just didn't see it. I was wondering if you could impliment one in the next version.

it's called the - operator.

Actually, I think Karl has a good suggestion, and the - operator wasn't the answer he was looking for.

Try to calculate how many seconds, minutes, hours, days, weeks, and years between two random times, and I bet it takes you several lines of PHP. Just because it *can* be done now doesn't mean it isn't worth considering making a function to help make it easier for people.

Is there a good reason why we shouldn't add some helpful date/time functions? If not, I'll be happy to take on the project myself.

Doesn't PEAR have a class which does that?
 [2002-03-17 13:37 UTC] shiflett@php.net 
I suppose it does. I should familiarize myself with PEAR more before I accidentally reinvent the wheel.

PEAR is somewhat nice and all, but this should really be CORE functionality.  What if they don't have PEAR and they're not allowed to install it or don't know how or don't even know it's there or....?

*Most* Functions in the Date/Time category should be core IMO since we already give them plenty of rope to hang themselves with other date manipulation functions.  This function is one that should be in core...I'm sure you'll dislike this example, but developers coming from VBScript 
will expect an equivalent to DateDiff().

We already have functions that *could* be done easily in userland as well...array_diff() is one of them.  So I don't buy that argument, nor the bloat argument as this should be a small addition.

Would like some feedback for and against this addition.
