516 -Once DS20L Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to DS20L. If DS20L fails to get the time from the server, DS20L will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).

If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**
