Systemd timers and chrony

Hello,

We are trying to set up chrony instead of systemd-timesyncd service,
everything works perfectly except for the systemd timers which fires
straight away when chrony updates time. It seems that systemd-timesyncd
does somethings to temporarily stop timers for time update, and this
doesn't work out of the box with chrony.

Is there a standard way to fix this problem, please?

This is quite a problem for our system, we don't have time backup and we
have timer to reboot system each day. Once we enable chrony the system
reboots in a loop due to time synchronisation.

Kind regards,
Krzysztof
