If OTT Navigator shows programme times offset from local time, check the device clock and time zone before applying a player-specific shift. A local shift can hide a system error and become wrong again when daylight-saving time changes. Use a channel-specific correction only when the problem is genuinely limited to that source. First determine whether every guide is offset or only selected entries. A device-wide timezone problem and one provider's schedule error require different corrections, and an apparently repaired display can still hide two opposing shifts.
Establish the real local time
Compare the device’s date, time and time zone with a reliable clock. A correct-looking clock with the wrong zone can still create scheduling problems. Check the date and selected timezone as well as the visible clock digits. A manually adjusted clock can look right while its zone remains wrong. Confirm whether the device uses a supported automatic time source and whether the selected zone follows local seasonal changes. If the player runs on an HDMI box, check that box's clock rather than only the television's settings.
Avoid stacked offsets
The device, provider and channel can each have time-related settings. Several compensating shifts make the setup hard to maintain and can produce a double correction later. Write down existing player, provider and channel offsets before changing them. Compare a known programme on more than one source to establish the affected scope. A correction applied globally can shift channels that were already correct, while an old manual offset may become wrong after the device timezone is fixed. Change the smallest relevant setting and keep a record of the original value.
Reload after a deliberate change
Use the developer’s documented reload process so the displayed guide reflects the current settings. Record what was changed and compare a known programme boundary. After the deliberate change, perform the documented guide reload and inspect a known programme start and end time. Also check whether the correct show appears under the correct channel; an association error can resemble a time issue. If only one provider remains offset with the device clock correct, report the specific source and example programme rather than adding several compensating shifts across the whole setup.
A practical sequence
- Correct device date, time and time zone.
- Remove unexplained compensating shifts.
- Apply a narrow source correction only if needed and reload.
An example
A one-hour guide error after a seasonal clock change should prompt a time-zone review before a permanent manual offset is added. Compare date, time and the selected region on the actual player device, then reload. If only a few channels remain wrong after correcting the system, investigate their source-specific guide data before applying a global shift.
Questions about this topic
Should I shift every channel if only one source is wrong?
No. First establish the scope of the problem.
Can two time shifts cancel temporarily and fail later?
Yes. Stacked corrections are difficult to maintain.
