[PVE-User] Time glitches?

[Alwin Antreich]

Hi Marco,

do you use a ntp server to sync your time?
  - Is the time equal on all cluster nodes?
  - If not configured, you can set it in "/etc/systemd/timesyncd.conf" (restart timesyncd).
  - Is your ntp server serving time correctly (no stratum higher 15)?
