Description kotrfa 2014-06-09 12:31:32 UTC 
Using systemd-timesyncd with network manager (e.g netctl) worked fine, but after using ONLY systemd-networkd, timesyncd doesnt sync time. After some time, it just shows status: "Idle." without any work.

Comment 1 kotrfa 2014-06-09 12:34:15 UTC 
By the way, no errors or log are present. The file /etc/systemd/timesyncd.conf is in it's defaults.
Comment 2 kotrfa 2014-06-11 16:31:45 UTC 
It seems to me that timesyncd just waits for "network configuration change". I guess that (somehow) timesyncd is runned after networkd and then waits for change. All you have to do is 

systemctl restart systemd-networkd


Here is example and steps to reproduce (after boot up, both networkd and timesyncd are enabled):


 ~ $ systemctl status systemd-timesyncd systemd-networkd

now restart networkd:
 ~ $ systemctl restart systemd-networkd


and the result:
 ~ $ systemctl status systemd-timesyncd systemd-networkd

Comment 3 Tom Gundersen 2014-06-30 20:28:07 UTC 
Is this still reproducible with current git?
Comment 4 kotrfa 2014-08-01 09:21:05 UTC 
I can reproduce it with 215-4.1 . Seems solved.
Comment 5 kotrfa 2014-08-01 09:21:24 UTC 
I can't reproduce it with 215-4.1 . Seems solved.
Comment 6 kotrfa 2014-08-01 09:22:24 UTC

Sorry - typo. I CAN'T reproduce it on same machine (as in post below).

Thanks for the clarification.
