New description:

 Windows XP SP2
 Vidalia 0.2.6
 Tor 0.2.1.22
 Qt 4.5.2
 Running TOR as client
 No changes in Tor's torrc
 Running TOR in English

 1) Launch TOR
 2) Wait for TOR to establish connections (icon turns green)
 2) Open Date and Time Properties (bottom-right of Windows desktop)
 3) Reduce/increase time by a few hours
 4) Connections start to increase endlessly
 5) Adjust Time back to original time
 6) Extra connections immediately close and disappear, TOR returns to
 normal number of connections

 Reason to do this is that, as I understand it, when javascript is enabled
 the webpage can detect your time zone, so I try to scramble that before I
 visit a website in which I want javascript to work.

 I will check back on this webpage every few days, in case there are any
 questions.

Comment:

 moving to "tor: unspecified" milestone. It's normal for tor to drop and
 reopen all its circuits when the time jumps a lot; this is how Tor
 normally detects coming out of hibernation.  Having "endless" connections
 would indeed be weird; is that actually happening, or is that just in the
 bug summary?

 Using torbutton should be adequate to keep websites from fingerprinting
 timezones.

 Is there a remaining bug here?
