I figured out what's happening and thank you for pointing this out.
The program no longer adds the daylight saving hour to the starting times of markets after your computer switched to the winter time, but it should do so retrospectively for all markets that had started during the daylight saving season. It was never a problem with real-time markets as their start time used to fall into the same time period as your local time. If you look at Time Machine markets that took place, say, in November or December last year, their starting time will be displayed correctly.
I will fix this in the next program update.
