Would somebody please collect this info on a wiki page.

On the other hand, the kernel probably wants to read the clock
early in the boot sequence so that the time is close.  I don't
want the kernel cluttered up with code to correct the raw
hardware reading (besides, the file with the info in it may not
be mounted yet), so writing out the correct time occasionally
seems like a reasonable idea.  I'd be thinking of hours or days
rather than 11 minutes, and I can do that from a cron job.

These are my opinions, not necessarily my employer's.  I hate spam.
