Thanks for your reply.

Yes, people have reported similar things on WinNT and WinXP:

   http://bugzilla.mozilla.org/show_bug.cgi?id=63720
   http://bugzilla.mozilla.org/show_bug.cgi?id=173431

I looked at the source code and found a call to localtime() in the C 
runtime library.  On MSDN I found that this has a quirk -- it is 
vulnerable to the TZ environment variable being wrongly set.  Mine was. 
  I removed the TZ variable completely and the times are now OK.
