      Description

      If the OS time is adjusted backwards by several hours, MaxScale will be killed by the systemd watchdog.

      Reproduced with:

      timedatectl set-ntp false
      timedatectl set-local-rtc false
      timedatectl set-time 04:51:14
      


      Original description:
      Hi Team,

      In MaxScale log the time was updating backwards during the maxscale crash.

      Here I have attached the maxscale log as-well as system logs too.. Please check it.
