9. DATE AND TIME
The system comes equipped with internal real-time clock (RTC) that keeps track of the current date and time. Once the system is up and
running, the user must set the correct date and time, otherwise the system will not operate properly. By default, after shutting down and
starting up the system, the date and time must be set again. In order to avoid manual date and time set up, please use the automatic date
and time synchronization feature (see 9.1. Automatic Date and Time Synchronization).

9.1. Automatic Date and Time Synchronization
This feature enables the system to set the date and time automatically without the user being involved in this process. The system sup-
ports the following methods of automatic date and time synchronization that are used automatically on system start-up and periodically
(by default – every 30 days):
• Via GSM network – Once enabled, the system automatically sends a date/time request to the GSM operator. This method is the
most accurate synchronization method. Some GSM operators might not support it.
• By SMS text message – Once enabled, the system automatically sends the SMS text message to its own phone number and re-
trieves the date and time from the SMS text message reply, as the included date and time is set by the SMSC (SMS center). This
method is not as accurate as the synchronization via GSM network, but always eective.
By default, synchronization via GSM network is disabled. To enable/disable automatic date and time synchronization via GSM network,
please refer to the following conguration methods.

NOTE: When setting up automatic date and time synchronization feature remotely, you may wish to restart the system when done.
For more details, please refer to 19. REMOTE SYSTEM RESTART.
NOTE: 0 value disables periodic synchronization.
NOTE: When both synchronization methods are enabled, the system will always attempt to synchronize date and time via GSM network
every time the system shuts down and starts up again and in accordance with the set period value. In the event of rst method’s failure,
the system will attempt to use the SMS text message method as a backup.
