Package: systemd-timesyncd
Version: 250.2-3
Severity: important
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
The stock configuration file that ships with systemd-timesyncd has all options commented out. Additionally, it doesn't set any default NTP server. This essentially means that Debian ships a package that will not sync to anything by default.
What currently ships:
[Time]
#NTP=
#FallbackNTP=0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org
#RootDistanceMaxSec=5
#PollIntervalMinSec=32
#PollIntervalMaxSec=2048
#SaveIntervalSec=60
What's expected:
[Time]
NTP=0.debian.pool.ntp.org 1.debian.pool.ntp.org
#FallbackNTP=2.debian.pool.ntp.org 3.debian.pool.ntp.org
#RootDistanceMaxSec=5
#PollIntervalMinSec=32
#PollIntervalMaxSec=2048
#SaveIntervalSec=60
... or something similar that would have a default list of NTP servers enabled in the stock configuration.

That should be fine.

Have you verified this is the case?
timesyncd should use either NTP servers obtained from DHCP or such or
use the built-in FallbackNTP if no other FallbackNTP is specified in
timesyncd.conf:
+---
| FallbackNTP=
| [...] If this option is not given, a compiled-in list of NTP servers
| is used.
+---[ man:timesyncd.conf(5) ]

default content on the NTP line or mention that the fallback servers
are compiled-in.
