Hmmm, odd.  After setting the hwclock with --utc, my /etc/adjtime has 
"UTC" but, when I cycled power, my system clock was off by my timezone.
Ahh, my /etc/adjtime has "0" instead of "UTC" on the second line.

OK, setting my hwclock to utc shows /etc/adjtime has "UTC", but after 
rebooting it gets reset to "0" (localtime), causing the incorrect time 
offset.
