i believe quozl found that when an F11-on-xo1 release is first
booted that there is no UTC or LOCAL line in /etc/adjtime.  at
that point the system will assume the hwclock reports UTC time. 
after the system has been rebooted once, somehow a "LOCAL" line
appears in /etc/adjtime.  this will change the relationship
between hwclock and system time, obviously.  not sure how or
where this fits into the current confusion.
