Match times are late/early

Match times are usually few hours behind (or few hours advance) because device time zone is not adjusted according to current location. Open phone settings, navigate to "Date & time" menu and select correct time zone.

If time zone is set to "Automatic" and match times are not correct, it means that your phone service provider (carrier) doesn't support that option and you need to adjust time zone manually.
