 > Downloaded os9, set RTC using hwclock --set --date . Confirmed time set
 with hwclock. Rebooted, and time was Jan 1, 00:00. Rebooted again, repeat
 setting time, reboot and back to 00:00 time.

 Reproduced as described.  The time is reset by the reboot.  I presume
 either the system reset or the firmware is the cause of the reset of the
 time.

 > Set time once more using hwclock, boot to OFW, examine time using select
 /rtc, get-time. Time is correct.

 Does not reproduce here.  Tried several times.  Time is incorrect; stack
 after get-time shows 10 0 0 1 1 64, .clock shows 0100-01-01 00:00:16 UTC.

 > Boot fully to Linux, and correct time is appearing now.

 The different result you got is concerning.  I wonder if it depends on
 when the reboot happens in relation to the clock value.  Can you tell me
 how you rebooted to OFW?  Or it might depend on when I test in relation to
 UTC.

 > There seems to be some kind of initial state after loading the os9 build
 that is causing the clock to reset.

 Yes, I agree.  My gut feel is OpenFirmware startup.

 I wonder it it might relate to #10989, where OpenFirmware doesn't seem to
 get consistent results either.
