WebJan 2, 2015 · Chrony is an NTP client and server designed to work well without a permanent network connection. It uses different algorithms to discipline the clock which gives chrony several advantages over ntp: Works well even with irregular polling of NTP servers, useful for laptops or systems without permanent network connection. WebYour problem seems to be that you're trying to accomplish a six year time change by skewing the clock, and giving up after one day.. If the skew algorithm drifts the clock by as much as one percent - which is quite a lot - it will take six hundred years to skew the clock that much. Even if the clock stands completely still, six years will need to elapse to step it …
