Date And Time; Sntp Is Available, But No Automatic Configuration By Dhcp Server - Siemens OpenStage 40 Administration Manual

3.5.4

Date and Time

If the DHCP server in your network provides the IP address of the SNTP server, no manual
configuration 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.
