Sigh. I don't know how to explain this any clearer.
RIGHT AFTER the clock is stepped, ntpd reports the time being off ... by
a lot (that's the 100-900ms I was talking about). During the 15 minutes
or so that ntpd takes to reset itself, the this clock offset changes very
little. I don't understand how that can be a frequency error. If it was
a frequency error, it would never get in sync, but it does.
Am I just not explaining this well?
