Why does the code work on local but not on live?

Question

go

On the locale, it outputs to the console

35316 2018-10-02 17:01:58 38 35316 17 899.41
35316 2018-10-02 17:01:58 38 35316 18 0
35316 2018-10-02 17:01:58 38 35316 19 0
35316 2018-10-02 17:01:58 38 35316 20 0

(Small excerpt)
On the server

80058 2018-10-03 00:27:50 35 0 0 0 
80058 2018-10-03 00:27:50 35 0 0 0 
80058 2018-10-03 00:27:50 35 0 0 0

The last three variables are always zero

  rows.Close()

Maybe your server is just in a different time zone?
