To ensure high time accuracy, you can also configure automatic time leveling with a so-called NTP server, e.g. one which supplies a time which is as accurate as a radio clock, using NTP (Network Time Protocol).
The Management Units are available as NTP servers for all units of the server via the private management network MCNPR. SU x86 and HNC are preconfigured with respect to NTP; AU configuration must be performed as required by the administrator responsible.
Effect on the time setting of the systems on the SE server
The time settings of the other systems are synchronized with the system time of the Management Unit. The Management Unit is the basic timer. Refer to section "Time synchronization".
When changes are made to the time management which affect the Server Unit, bear in mind that the time settings in BS2000 systems and of XenVMs that are started later are also affected. Here you should in particular avoid large leaps in time which are caused by setting the time manually.
Details on BS2000 are provided in the "Synchronization of the system time" section of the "BS2000 OSD/BC System Administration" manual [10].

The System time tab displays the NTP servers which are configured for automatic time synchronization and the local time of the MU.
Adding or removing an NTP server
> | To add an NTP server, click Add NTP server in the Time synchronization with NTP server group, and after making the necessary entries confirm the action. |
> | To remove an NTP server from the NTP configuration, click the Remove icon by the required NTP server in the Time synchronization with NTP server group and confirm the action. |
Changing the local time
You can only change the local time if no NTP server is active.
Changes to the time can also have an effect on productive operation. See also section "Effect on the time setting of the systems on the SE server".
> | In the Local configuration group click the Change icon, and after making the necessary entries confirm the action. |
