Configuring the Avaya DECT Mobility Manager

Time zones

The local time and date displayed on Avaya 3711 DECT handset devices depend on the IP
region the handsets are located in. Each IP region is configured to a certain time zone (see also
Backup on page 48). Based on this the local time can be calculated individually depending on
the current date and the daylight savings time rule. A time and date resynchronisation of the
Avaya 3711 devices is described in Licensing on page 40.
In the time zone section the Avaya DECT Mobility Manager provides all available time zones.
They are set per default with their known daylight savings time rules adjusted to the Universal
Coordinated Time (UTC). The difference to the UTC time is shown in the "UTC Difference"
column. In case of a daylight savings time rule this is also marked for each time zone.
There is a possibility to change the time zone rules for maximal five time zones. Changed rules
are marked with a bold time zone name in the table. The changes are saved in the configuration
file and are restored after each Avaya DECT Mobility Manager boot up. The default button sets
all time zones back to the default values and deletes the changed time zone rules in the
configuration file.
