• in some cases it is needed get actual time from network.
    To get the time you can use AT#NITZ (for detailed information please read in documentation AT-Commands).

    NOTE: unfortunately is this service not from all Providers supported!

    In this case there are two possibilities:
    1: using the internal RTC with an external backup batterie.
    2: make a HTTP - Request. The Server will you send the time too.
