Diagnose the pattern
- Every channel is shifted by the same amount: check device time zone and player-wide EPG offset.
- Only some channels are wrong: inspect channel-to-EPG mapping or source data.
- Listings were correct and then became wrong: refresh the guide and check for app, source, or daylight-saving changes.
- Programme titles are missing rather than shifted: investigate guide download and mapping instead of adjusting the time offset.
Troubleshooting steps
- Compare the device’s displayed local time with a reliable clock.
- Confirm the device time zone and automatic time settings.
- Check the player’s EPG settings for a time-zone selector or offset. Do not change it until you know whether it is set to local time or another standard.
- Refresh the guide data if the app provides a separate EPG update.
- Compare a known upcoming programme on several channels.
- If only specific channels are wrong, check their guide identifiers or ask the provider to confirm the correct mapping.
- If all listings remain shifted, send the app name, device model, approximate offset, and example programme time to support. Do not include private credentials.
Why repeated refreshing may not help
Refreshing downloads the same source again. If the source contains incorrect times or the app applies the wrong offset, repeated refreshes may reproduce the same error. Confirm settings and mapping before repeating the operation.
FAQ
Why is my EPG one hour ahead or behind? A time-zone or daylight-saving mismatch is one possibility, but verify the device and app settings rather than assuming a fixed correction.
Why are only a few channels wrong? Their EPG identifiers may point to incorrect or differently timed guide entries.
Can I fix EPG time by changing the TV clock? Correcting an inaccurate device clock may help, but do not alter a correct system clock just to compensate for bad source data.
