I have spent some time looking into this.  It can be done, but it will be 
difficult to do.  Problem #1 is that the in-kernel timezone support is 
minimal, so doing reverse-timezone conversions from the RTclock are 
difficult, and IMHO don't belong in the kernel.  Secondly, if the 
time/date on a ufs partition is more recent than the RTC, the kernel 
assumes a bad RTC and uses the value from the ufs partition, and this 
value is set before /etc/rc is run.  This means that if you're in the 
western hemisphere, your clock creeps forward a few hours each time you 
reboot.  

The only reasonable solution I can see is to have a user-level program 
that directly getis its value from the RTC and resets the kernel time.  
Unfortunately, the RTC is not consistent between Amiga models...

UGH!
