Date and Time
If the DHCP server in your network provides the IP address of the SNTP server, no manual con-
figuration is necessary. If not, you have to set the
SNTP IP address
parameter manually.
For correct display of the current time, the
Timezone offset
must be set appropriately. This is
the time offset from UTC (Coordinated Universal Time). If, for instance, the phone is located in
Munich, Germany, the offset is +1 (or simply 1); if it is located in Los Angeles, USA, the offset
is -8. For countries or areas with half-our time zones, like South Australia or India, non-integer
values can be used, for example 10.5 for South Australia (UTC +10:30).
If the phone is located in a country with daylight saving, the administrator can choose whether
daylight saving time is activated manually or automatically. If
Daylight saving
is enabled, and
Auto time change
is disabled, daylight saving time (DST) is in effect immediately. If
Auto time
change
is enabled, daylight saving is controlled by the
Time zone
parameter. This selects the
daylight saving time zone which is characterized by the start and end date for daylight saving
time.
The
Difference (minutes)
provides the time difference for daylight saving time in minutes. This
parameter is required also when
Auto time change
is enabled. In Germany, for instance, as in
most countries, this is +60.
