Write down the two locations
Open the Freeview app’s More tab and inspect TV Guide Location. Freeview’s support describes selecting the region you want to review there. Then note the phone’s current time zone and the date of the programme listing you are comparing.
For example, somebody planning television for a relative in another state may deliberately choose a guide region different from the phone’s physical location. That is a planning scenario rather than proof the app detected the wrong place. Keep the intended guide location, device clock and programme date together in your notes.
Correct the actual mismatch
Freeview’s clock help directs viewers to the phone’s date-and-time settings and describes automatic time-zone selection for the current location. Its guide-location help separately describes choosing a region inside the app. Review both rather than adding a fixed hour to every programme yourself.
If you intentionally changed the phone’s time zone for a comparison, note the original setting so you can restore it afterwards. A device-wide clock change can affect other time displays, so use the smallest change that addresses the mismatch you identified. Close and reopen Freeview after correcting the relevant setting, as its support guidance describes.
Compare the same dated event
Check one programme on the intended channel and date after the change. Keep its local start time and channel edition with the result. A state-based programme edition and a device clock can each influence what you think you are comparing; matching only the title is not sufficient.
If the guide still differs, record the app version, selected guide region, device time zone and the exact dated listing. That gives Freeview a reproducible question. Avoid retaining an unexplained manual offset as a permanent fix, because a later seasonal clock change or a change of selected region can make the old adjustment wrong.
