Server time configuration

I want to know how to set ChirpStack time. My terminal report time is different local time,.this deviation is 8 hours. For example :slight_smile:
{“time”:“2019-12-24T22:58:44Z”,“rssi”:-123,“loRaSNR”:6.8,}
local time is 2019-12-24 14:58

The trailing Z indicates UTC.

Thanks,I know it. But where I can change time format.
Looking forward to your answer,thanks again
