Transition from daylight saving time (DST) to standard time is not handled properly

[alecigne]

On the day of transition from daylight saving time (DST) to standard time, ambiguous local time values exist between 1:00 AM and 2:00 AM since this hour happens "twice" locally. As SomaFM's song history webpage display local times only (example here), computing a correct UTC broadcast time during this period becomes annoying (e.g. deciding between DST and standard time for two tracks played at 01:30 AM).

For the sake of simplicity, all broadcasts during this period are thus listed as being played in the DST timezone (one time correctly, and another time incorrectly during the "second 01:00 AM hour"). This will create a "void" of one hour in a UTC timeline.

Example: on 2021-11-07 at 01:00 AM #1 in Los Angeles, it was 2021-11-07 08:00 AM UTC. On 01:00 AM #2, it was 2021-11-07 09:00 AM UTC. However, no broadcasts will exist at this UTC hour.
