Record the actual boundary
Note the channel, displayed start and stop, and the local date where you are watching. Do not send only “12:30” or “after midnight”; those phrases leave several possible interpretations.
For a replay, include the original transmission date shown by the service as well as the local time you attempted playback. The date used to organise the replay library may not be the same date you are currently viewing.
Keep the zone with the timestamp
A numeric time without a zone is incomplete for a cross-region comparison. XMLTV supports programme timing information, while the player may convert it for the selected local zone. Check the actual configuration instead of assuming that every screen uses the source broadcaster’s clock.
Location-based time-zone rules also change over time. A permanent manual offset can become wrong after a civil-time change or daylight-saving transition. Use the exact location and date when checking an example.
Compare the neighbouring listings
Look at the programme before and after the affected entry. If every listing moves at the same boundary, investigate conversion or date selection. If one item alone has a wrong stop time, preserve that narrower source-data example.
Do not shift the whole guide solely because a programme appears under the previous day’s late-night schedule. Some interfaces group overnight entries by a broadcast day rather than by the way you expect to browse the calendar.
Make the report unambiguous
Use a full example such as the displayed date, local city, programme title and both the shown and expected time. Do not include private guide URLs or account tokens.
If you apply a supported correction, test both sides of midnight afterwards. A change that makes tonight’s entry look right but moves tomorrow’s schedule incorrectly needs to be reconsidered. Keep the original settings so the comparison can be repeated.
Questions about this guide
Is a programme under yesterday’s schedule always wrong?
Not necessarily. Check whether the interface groups overnight broadcasts and what time zone it uses.
Why include the date as well as the time?
Midnight boundaries and zone conversion can change the calendar day. A time alone cannot identify the intended occurrence.
