DevTimeReq wrong time to Device

Hi,
whenever i force a time synchronisation at my device, its getting a completly wrong time.
Where is the time specified that my device get from the server?

What device and how are you forcing the synchronization?

Its a luminare controller and i am forcing the synchronization with an downlink command.

Assuming we are talking about the DevTimeReq / Ans, ChirpStack tries:

  • Using the GPS time from the gateways, failing that
  • Gateway time, failing that
  • The server time

Hi Brocaar, can I switch off “using GPS time from GW”?

as results it delivers wrong GPS time to the devices:

You can not. If the gateway provides a GPS time, then ChirpStack will assume that that time is correct. It might be better to resolve this issue at the gateway level instead.
