AFAI understand it the systemd-timedated.service helps setting clock and |
16 |
time-related settings ... and if you use it to enable NTP syncing, |
17 |
systemd-timesyncd.service will actually take over the part of syncing |
18 |
with ntp servers. |
19 |
|
20 |
I also preferred chrony over ntp for the last year or so. Better with |
21 |
laptops etc. and quicker to correct time when there is large offset. |
22 |
|
23 |
What I haven't yet fully understood: |
24 |
|
25 |
daemons like chrony bring a specific settings file for |
26 |
systemd-environments, in this case: |
27 |
|
28 |
/usr/lib/systemd/ntp-units.d/50-chrony.list (saying "chronyd.service") |
29 |
|
30 |
In the same directory I see 90-systemd.list (saying |
31 |
"systemd-timesyncd.service"). |
32 |
|
33 |
As far as I understand this: |
34 |
|
35 |
if other ntp-software is installed, systemd-timedated.service uses the |
36 |
ntp-unit with higher priority (in my current case chronyd.service) for |
37 |
ntp-syncing. |
38 |
|
39 |
So you may use the systemd-timedated.service to do your settings and in |
40 |
the same setup let it use another ntp-daemon to actually do the syncing |
41 |
behind the curtains. |

Generalized interface with choice --- nice, isn't it? |
44 |
|
45 |
;-) |
46 |
|
47 |
but maybe I misunderstand. |
