Dear All
Im sending some data and read them with phone app made with app inventor. Everything works nice except one thing which is not big but let me ask. Looking at the field chart date and time are exactly as send but when I read them using field created_at time is allways one hour less then the right one like on the chart is there a way to read this right or to do some math!?
Best regards and thank you

What are you setting the timezone parameter in your GET request? See documentation here.
Can you post the exact GET request you are making? Please do not post the API key so it remains private.
Method is get
I have tested timezone command before you medtioned it but the same

I see that the time difference between Belgrade and UTC is 1 hour. So, if you have the API call correct, you will see a 1 hour difference between the response with the timezone parameter and without it.
Here's the call to retrieve the data in UTC:

Note the "created_at". Now, apply the timezone parameter and note the "created_at"; Exactly 1 hour apart, as expected.

Dear Vinod
Solved with timezone=Europe/Belgrade Why in tutorial you put timezone%2America/New_York instead of timezone=America/New_York

EDITED
It should read %2F, to be URL endcoded. The '/' character gets written as %2F. I checked the doc page, it is correct, you missed the 'F'.
Thank you again for your effort
