[Solved] systemd-timesyncd

K3N8 · 2018-05-22 11:46:02

Hi,

I am trying to get the systemd ntpd variant working. I have enabled en started the systemd-timesyncd and systemd-timedated services. After the initial sync noting happens?! Shouldn't it be syncing once every so-and-so minutes?

Thanks.

Alexander

How are you determining that it isn't syncing?

The default config contains...

...
#PollIntervalMinSec=32
#PollIntervalMaxSec=2048

so the max interval is about 34 minutes between syncs.

OP, you may be seeing this bug https://bbs.archlinux.org/viewtopic.php?id=236598. That bug has been fixed in the systemd master branch but still exists in the current Arch systemd 238.76-1 package.

I have looked in the wrog place.

journalctl -r -u systemd-timesyncd

I should have looked at:

stat /var/lib/systemd/timesync/clock

Everything is ok.

That doesn't sound right. You are guaranteed to see a "Synchronized to time server xx.xx.xx.xx" message in the output of your journal seconds after boot if systemd-timesyncd is running correctly.

journalctl -b -u systemd-timesyncd | grep "Synchronized to time server"

Note that the /var/lib/systemd/timesync/clock file is first updated after boot at the same exact time as the above message is written. Also, that file can only be viewed/stat by root.

It only shows syncing on startup

journalctl -b -u systemd-timesyncd | grep "Synchronized to time server"

'man systemd-timesyncd' suggests that the /var/lib/systemd/timesync/clock file should contain the timestamp of the last successful sync, but the file size (grootte) is 0 (empty), so I would second the opinion that there is a bug. Either that or the documentation is wrong.

man systemd-timesyncd wrote:

FILES
       /var/lib/systemd/timesync/clock
           This file contains the timestamp of the last successful
           synchronization.
