NTP

When using external time servers (NTP servers) it must be taken into account that they have to be configured in all MUs.

This must be done in SE Manager under
  Hardware -> Units -> <server> (SE<model>) -> <unit> (MU) -> Management, tab System time.

In case of different locations, the NTP servers in use can be different, but for the MUs of one SE Server they should always be identical.

Further details can be found in the manual “Administration and Operation“ [1] and in the online help of the SE Manager.
