Yes you are right, my mistake. I think I in the code had the example from the API manual: “change location to GPS coord 42.01,-75.22”
where the minus sign was still in the second argument there as I just follwed the example and changed the values and the minus sign was still intact.
The time is correct when I tried it manually now. Yes, I can set the location in the UI also which is a better idéa.
Thank you for your help!
