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.

Other location records with this same transition include Australia/Broken_Hill, Australia/Adelaide. Confirm the intended location from your actual broadcaster.
