Any ideas what I can change to let the hardware clock be set by ntp? Uli In fact, the hardware clock is never set by NTP (that is, not directly). What output do you get, when you call "/etc/init.d/ntp ntptimeset" manually? Does it work when you call "hwclock -w --debug", i.e. In my case the server in /etc/are not reachable and therefore /etc/init.d/ntp ntptimeset has no effect.

I guess the problem is that bit 64 of the adjtimex status is never cleared so the kernel does not run in the "11 minute mode". And I just tried it: "/etc/init.d/ntp ntptimeset" correctly sets the RTC on my 12.3 system. takes the first reachable and non local server from /etc/ If you have all servers in an include file /etc/init.d/ntp ntptimeset does not work.
The greater the stratum of the server, the greater the distance between that server and the reliable time source.
To ensure that your network devices display the most accurate time, you need to configure the NTP protocol and link your devices to a reliable time source. You could purchase a hardware time device that obtains the time via GPS or some other method.
An NTP client synchronizes the time and date with an NTP server.
The NTP server should be a reliable source, such as a time server on the Internet.
A number of free public Internet time servers are available.
