> We are having a lot of very small embedded boards (Arduino) without a RTC function (Real-Time-Clock). If we want to insert the data over MQTT, with the IoTDB-built-in-MQTT-service, the insertion only works, if we provide the timestamp inside the MQTT-JSON-format, like on your example: [https://iotdb.apache.org/UserGuide/V0.12.x/Communication-Service-Protocol/Programming-MQTT.html]
> It would be nice, if the timestamp can be added automatically by IoTDB on database insert, if no timestamp is provided inside the MQTT-JSON structure.
> IoTDB Version 0.12.1
