I've been down the exact same road. With the same results.

My problem is even simpler. I want my computer to periodically read a
time standard someplace and set the pc/xp hardware clock
appropriately. I haven't been able to find out whether ntp sets the
local clock or replaces it. I know how to set the cmos clock manually.
Does ntp know how?

Maybe someday I'll have more than one machine. Not yet, though.
