Is there a way to show uptime on the phone (on a non-rooted pre in this case)?

A couple hours after I updated my gf's phone to 1.1 it was sitting on the desk and I noticed it was at the Palm logo booting back up. Seems it must have randomly restarted. I don't believe it has done this before but I figure only way we can tell is to keep an eye on the phone's uptime, but I've yet to find a way to do that.
