timers in IE

timers in IE

 I'm trying to use a jQuery timer but it doesn't seem to work in IE. Then I tried plain old setInterval and it doesn't work in IE, my eternal curse. I'm reading on the net that IE doesn't support setInterval. Am I getting that wrong or if I'm not, how do you set a recurring interval in IE?  What's happening is the function I'm calling only gets called Once, no matter what I do.
