  Yeh, I agree, timekeeping isn't going to be that great on FreeBSD/PPC 
at the moment.

  OpenFirmware is used to read the RTC, but it's never written back: any 
attempt by NTP to set the time is silently ignored.

  This will be fixed when the external PMU is accessed directly (needed 
for notebook kbd/trackpad access), so the time can actually be set.

later,

Peter.
