Thanks to everyone who's written with clock suggestions, I've gone with AboutTime, which is working perfectly. So now my clock is accurate, though I still don't understand why it can't be accurate all on its own. I've never had this problem wih any of my computers before. Oh well, I'm not worry about it, heck, it's a beautiful day outside, so I'm going to enjoy it. And not worry about silly things like computer clocks, or computers.
