The missing wall time cannot represent a programme instant

The clock moves from 00:00 to 01:00 at the boundary. Round-tripping 00:30 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.
