Date and Time
The date and time are displayed in the phone's status line.
The date and time are needed to log incoming, outgoing and missed calls and to control various functions on the phone, such as automatic updates.
* Note: If you change the time zone, the time stamp assigned to all data on the phone is adjusted to suit the new time zone.
