And that's why there's adjtime. Or by "system clock" do you mean the hardware clock? That's not what I asked about. Outside of microsoft world, "system clock" means that little timekeeper in the *nix kernel.
In the context of my post, it was quite clear that I meant the system clock and that I knew what I was talking about. The only reason for you to bring up this straw men is that you don't have arguments left.
[about system clocks] It's like talking about all the wood you have to use for your central heating. Times have changed.
[about ntp] The script is 25 or so years old, predating even RFC958.
Ahem, what do you want now? That one shall use a "cron job of 25 years ago" (the one that I wrote for things like this is actually some 30+ years old, but *I* grow out of writing such special scripts just for myself some 25 years ago), or that one shall acknowledge that "time has changed" and that one uses ntp nowadays? Your ramblings don't make any sense at all. You are incoherent and obviously ask questions not for discussion but for trolling. Thank you very much for providing another entry for my KILL file.

Just a thought, If your clock drifts several minutes per _month_, it can be put back in sync with ntpdate (or its modern equivalent). If your clock drifts several minustes per _day_ it could indicate that either your mobo is deteriating (the battery, while switched-off) Or your ntpd uses a pool in which a highly unreliable ntp-time gives you sometimes the "wrong time". Specially when using kerberos-tickets, a drift of over 300 seconds can causes a lot of nasty effects. hw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not if you define several ntp servers to query from. A ban one is discovered and discarded. - -- Cheers, Carlos E.
