Date and Time
You have the following options for determining the system time (local time):
ISDN/Manual
The system time can be updated via ISDN, i.e. with every existing external connection the
date and time are taken from the ISDN. The date and time can also be entered manually,
e. g. if time and date are not sent in the ISDN or no time server is provided. The time re-
mains for approx. 3 hours after the system's power supply is switched off.
The clock switches from summer to winter time (and back) automatically. This is independ-
ent of the exchange time or the ntp server time. Summer time starts on the last Sunday in
March by switching from 2 a.m. to 3 a.m. The calendar-related or schedule-related
switches that are scheduled for the missing hour are then carried out. Winter time starts on
the last Sunday in October by switching from 3 a.m. to 2 a.m. The calendar-related or
schedule-related switches that are scheduled for the additional hour are then carried out.
Time server
You can obtain the system time automatically, e.g. using various time servers. To ensure
that the device uses the desired current time, you should configure one or more time serv-
ers.
