Package: systemd-timesyncd
Version: 245.6-1
Severity: important
systemd-timesyncd no longer seems to work. I couldn't find any reason in the logs.
Now there's a 5-second delta!

If I understand the "timedatectl show-timesync" output, it stopped
working on 2020-07-06 20:06:16 CEST. I suspended my laptop shortly
after this time. But I do that several times a day. The only awkward
thing I could notice in the logs is thousands of messages
