Date and Time Display 
 
Implementing features, see also Manager E Date and Time Display

Definition  
The system contains a real-time clock and a calendar. Every telephone with display (optiPoint, OpenStage) shows the time and date information generated by this clock.
In the case of digital trunks (not for U.S.), the date and time are set automatically, provided that the information is transmitted from the central office (during the first outgoing call). The system changes automatically from standard time to daylight savings time (and vice versa).
In IP networks with HiPath 5000, clock synchronization is no longer implemented via ISDN but via the SNTP protocol.  
When manually setting the time of day, observe the following:
 •   after a system boot
The "ISDN time" always overwrites the time that was manually set after a system boot when the first outgoing ISDN trunk call is made.
 •   when the system is running
If the time that was manually set differs from the "ISDN time" that is received by 2 - 70 minutes, the system uses the "ISDN time".
If the difference is < 2 minutes or > 70 minutes, the system uses the time that was manually set.
If it is not possible to synchronize using the ISDN trunk, the switchover data can be entered in a table that is internal to the system. Edit the table using HiPath 3000/5000 Manager E.
The day and month when daylight savings time should begin or end is specified for each year. The system switches over, as appropriate, at 2 or 3 a.m.
The date can be displayed in the following formats:
 •   Europe: 20.JUN 01
 •   USA: JUN 20.01
 •   International: 20 JUN 01
 •   International 2: 20.06.01
