It might be reasonable > to do I'd say that if the time was off by more than a few seconds (remember, we're talking about secure machines here), a reboot might not be inappropriate. But if the machine is not rebooted, xntpd will step the clock, the step will be clamped to +1 second, and xntpd will recompute the delta, decide another step is in order, etc. So the time will slowly reconverge. The behavior before (at least for negative deltas) was that the clock would continue to drift out of control even if there were suitable peers for xntpd. -- echo afnlre@dhnpx.xsh.pbz |\ : "Quick man!
