I’m not seeing your timestamp being added anywhere here, am I missing where that happens?
Also, I found node-red-contrib-influxdb (node) - Node-RED which says:
Note how timestamps are specified - the number of milliseconds since 1 January 1970 00:00:00 UTC. In this case do not forget to set “ms” in “Time Precision” (Advanced Query Options) of the “Influx Out Node”.
