      org.freedesktop.ModemManager1.Modem.Time:
      @short_description: The ModemManager Time interface.

      This interface allows clients to receive network time and timezone
      updates broadcast by mobile networks.

      This interface will only be available once the modem is ready to be
      registered in the cellular network. 3GPP devices will require a valid
      unlocked SIM card before any of the features in the interface can be
      used.

        GetNetworkTime:
        @time: If the network time is known, a string containing local date,
        time, and (if available) UTC offset in ISO 8601 format. If the network
        time is unknown, the empty string.

        Gets the current network time in local time.

        This method will only work if the modem tracks, or can request, the
        current network time; it will not attempt to use previously-received
        network time updates on the host to guess the current network time.
