After approximately 3 hours of running Tor/Vidalia, I find that all my network connections drop off, and the following error message appears in the log.

[20:14:37] Your Computer's Clock is Potentially Incorrect - Tor has determined that your computer's clock may be set to 28730 seconds in the past compared to the source "DIRSERV:". If your clock is not correct, Tor will not be able to function. Please verify your computer displays the correct time.

I don't know if this stops things working or not, but though I'd check.

The advanced log doesn't mention the time (see below)

The simple question is if you sync to a timeserver of some sort, if not, you should. It's also possible the dirserver referenced is out of sync.

Ok. When comes out (sometime this month hopefully), this problem should be gone. Thanks!
