my least favorite type of date/time/timezone data in this current project i'm working on would probably be "unix timestamp but in local time"

getting those to parse correctly in my code is always an adventure, and the best part! is that:
1. the gtfs-rt standard calls for utc unix timestamps, which are pretty much the industry standard
2. the government document explaining the data source doesn't specify and just kinda implies to follow the gtfs-rt standard
3. when i tried following the standard the data was wrong (because they actually use local time unix timestamps!!!)
4. troubleshooting it and realizing what they did took ages because i had to be certain that the problem isn't whatever python/js library i tried using
