IE doesn't support setInterval?

IE doesn't support setInterval?

 I was trying to use a jQuery timer to repeat a function at intervals, but it didn't work in IE. Then I read that IE doesn't support setInterval, which seems amazing. Did I read this right? And if so, what do I use in jQuery to keep repeating a function at intervals? I've tried a few things and they all bomb out in IE, just doing something once, although they work in FF. What works in the execrable IE and real browsers?
