What the time zone rules produce
| Moment | Local schedule time | UTC |
|---|---|---|
| One second before the change | 2025-03-30 00:59:59 GMT | 2025-03-30 00:59:59 UTC |

The missing wall time cannot represent a programme instant
The clock moves from 01:00 to 02:00 at the boundary. Round-tripping 01:30 from local time through UTC finds no matching instant.
If the EPG shows the wrong slot
Ask for a corrected local time or the explicit UTC instant. Check the exporter before shifting the whole guide.
Other location records with this same transition include Europe/Dublin, Europe/Lisbon, Atlantic/Madeira, Atlantic/Canary, Europe/London. Confirm the intended location from your actual broadcaster.
