What the time zone rules produce

The missing wall time cannot represent a programme instant
The clock moves from 02:00 to 03:00 at the boundary. Round-tripping 02:30 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.
