This is on a Raspberry Pi 3 with Raspberry Pi OS Bookworm 64 Bit,
ie. Debian 12. I have uninstalled systemd-timesyncd and installed
ntpsec, then have commented out the 4 NTP servers
{0,1,2,3}.debian.pool.ntp.org, and instead added my own server with
server -6 my-ntp.my-domain
When I call ntpdate my-ntp.my-domain manually it steps the time as
expected. But then, ntpd doesn't sync the local clock to the NTP
server, although it seems to consider that server's clock stable:
$ ntpq -p
remote refid st t when poll reach delay offset
jitter
=================================================================================
+my-ntp.my-domain 237.17.204.95 2 u 29 64 377 0.4696 -0.0378
0.0196
$ ntpstat
unsynchronised
polling server every 1 s
I usually see a '*' in the first row to indicate that the local clock
is in sync with that server. The ntpq(8) man page says about +:
+ │ included by the combine algorithm
In /var/log or with journalctl I don't see any hint what might be the
reason. When I let it run, the offset as shown by ntpq grows over
time.
