>I am almost certain it's not the battery. If my machine stays off for a few days (rare occurance) there is no time loss. You would expect a gradual, metered time loss if it were the battery.

So, from other posts it appears a non-battery-related time leak may be fairly common - I was only really upset once when I missed a getting in a late eBay bid due to the leak, since then, I keep a clock right near the machine.

We never see it at here at work, since all the local clocks are reset to a Central LAN time at every login - Maybe you could use Doug's link to do that manually, or maybe even set it up to do it as a scheduled service, if it's really important.
