Yes, I know you can rig it, but...
Oops, you lose one point; you didn't take care of remote login (which also
doesn't go through /etc/default/login).  It's not entirely a no-brainer,
either (or else my state of no-brain-ness is at a lower level than yours:-),
because I'd probably screw up every time I reset the clock by resetting it
to local time instead of GMT.  Natch, I don't reset the clock that often,
only enough to compensate for drift (but then, that's exactly what would
cause me to screw it up--I wouldn't do it often enough to remember).

[Gripe digression:  Whose &^%$#!! idea was it to use a 1.193182 MHz
oscillator, anyway?!?!?  If they'd chosen a sensible frequency on the AT,
the 8254 could be programmed with a value that wouldn't drift noticeably.]

Your suggestions are good, but I still wish there were a way to wire GMT
into the CMOS clock handling without the timezone games.
