4.1.8  Time and Date 
This option sets the date and time on the phone, but can be overwritten by the time server when 
the phone is restarted. 
4.1.8.1  Time Server 
The phone acquires the time and date from the time server. The time server is already assigned, 
and this option requires an administrator password. Talk to your administrator if your phone has 
any difficulty with the date and time. 
4.1.8.2  Set Time and Date Manually 
 
If you set the time manually, the phone will not try to synchronize the time with the time server until 
the next time the phone is restarted. 
Go to Preferences > Time and Date.
