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. After shutting down and starting up
the system, the date and time must be set again.
By default, in order to avoid manual date and time set up, the automatic date and time synchronization feature is enabled
(see
9.1. Automatic Date and Time Synchronization
). However, some SIM-card providers may not support this service.

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 supports
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
retrieves 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 effective.
By default, synchronization via GSM network is enabled. To disable/enable automatic date and time synchronization via GSM network,
please refer to the following configuration methods.
