I told Windows to go with UTC.  Takes a while to get used to the
display (if I bother to look).  I don't care much about what Windows
displays anyway (I'm rarely there...).  I realize that this doesn't fit
others' needs, though.

Linux naturally is set to deal with the HWC set to UTC, which a while
ago was good considering some bug in libc, IIRC. (That's when I made
the jump form local to UTC.)

In a completely rational society, the best of us would aspire to be 
_teachers_ and the rest of us would have to settle for something less, 
because passing civilization along from one generation to the next 
ought to be the highest honor and the highest responsibility anyone 
could have.     - Lee Iacocca
