I am certainly no expert on the workings of NTP, but I thought NTP worked with a "clock discipline" to achieve the best time and synch.
Yep. It compensates for the delay between server and client and then the error. I posted the link about it in another message.
The 60kHz from WWVB (or MSF Rugby, now gone), just like 77kHz from DCF77 or the 243kHz longwave carrier from Kalundborg are highly accurate frequency standards. They are excellent for a PPS signal for your local reference clock. Is that what your Radio Shack device does, act as reference clock? I have a DCF receiver, but it only provides the time signal, not a PPS signal. GPS receivers are also popular as PPS providers.
No, it's just a clock that sits on my window sill. It has no output other than the display. As I mentioned, it only syncs periodically throughout the day. The display shows when it's attempting to sync and whether it's synced in the past few hours. Many years ago, Heathkit had a kit that received WWV or WWVB and produced an output that could be read by a computer. http://www.schaffrath.net/mac.html -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
