systemd-timesyncd is not installed by default

First, thanks for making these images, I'm trying to use it to build an Octoprint server on an old PCDuino3 nano.

It boots perfectly and seems to run reasonably well, but it seems NTP does come up on start and sync the time. The lack of synced time creates issues with SSL certificate validations which impacts the ability to download packages including ntpdate.

I can manually set the date by copying it from another machine

# Time Synced machine
date +%s # copy time from a synced machine

# On the PCduino - set the time to something close
date -s "$(date -d @1670738614)"

After ntpdate is installed, I can manually sync time by using ntpdate tick.utoronto.ca , obviously it would be far better if the images automatically synced their time.

By default it uses NTP servers returned by the DHCP server. You need to either configure your DHCP server or configure Debian.

What package is responsible for that in the image so I can investigate further?

Is it networkmanager? I couldn't find anything with dpkg --get-selections | grep ntp

Reading up on it a bit more, I guess this is possibly supposed to be handled by systemd's systemd-timesyncd.service unit...

Looks like it's not working for me, maybe the lack of /etc/systemd/timesyncd.conf is the issue?

systemd-timesyncd wasn't installed by default, adding systemd-timesyncd fixed it instantly:

apt install systemd-timesyncd

Please note you cannot install or update anything, including systemd-timesyncd, on any of these images until you manually bring system time close to current after installation using the following command (example for just now, modify as required):

date --set="9 JAN 2023 22:48:00"

AFTER you do

apt update && apt full-upgrade

you can install with

apt install systemd-timesyncd

Hope this helps
