Hey Tony.  I know this is an old email (April), but you wouldn't happen
to have the complete fix for this, would you?  I tried what I thought
you were describing and it didn't work.   Also, does using _tzset mean
TZ has to be set?  The _tzset page on msdn.microsoft.com seem to imply
it did, but the Time Management Routines page seems to imply that TZ
only overrides the system settings.  I tried both ways and neither
worked.

I found Chuck's patch on mail-archive.com, but your mail seems to imply
that Chuck's patch was unecessary and there is a smarter fix.

I did find a note on the gmtime page that says that "The target
environment should try to determine whether daylight savings time is in
effect. The C run-time library assumes the United States's rules for
implementing the calculation of Daylight Saving Time (DST)".  Does
anybody know what this means?
