I'm using Ubuntu Mate 15.10 on a F.Siemens laptop. I'm facing a time drift issue that I'd need some help with.
The time drifts by as much as 15 minutes in a 2-3 hour span. Forcing an update (with sudo ntpdate
after stopping then restarting the service) works, but drift eventually returns. I noticed that at some point the clock corrected itself, which means npt does at some point run. But I'm a bit puzzled about its frequency, because on some occasions it seems to correct the time once in, say, two hours, while on others many hours can pass by without any correction.
My question is: which file/setting do I have to edit in order to a) check that the service is indeed active; b) adjust the frequency.
timedatectl status
? Does it say "Network time on: Yes" and "NTP synchronized: yes"?systemctl restart systemd-timesyncd
