On accurate time

These three links were posted in a Novell support group. They describe in good detail how NTP works. For those familiar with Timesync, this is why ntp and timesync are different animals.


From my own experiments, NTP clients quickly determine that Timesync machines are bad sources of time. The convergence algorythum used by Timesync is piss-poor as far as NTP is concerned. Historically NDS timestamps on the second, so it was only important to have time accurate to the second. Timesync does that. NTP provides time accurate to the .010 second in most cases, which is a very different animal. A downside to using NTP on NetWare is that NTP takes a lot longer to get 'in sync' than Timesync does.
