Since I have no experience living in an area with daylight saving time, I'm more curious about people living in an area with daylight saving time, if they usually go to bed at 10pm, do they still go to bed at 10pm after the time zone change?

\nInteresting topic, thanks for raising it.
\nJust a side note on DST, there has been a severe dataset issue with respect to recording DST. You can check https://www.kaggle.com/competitions/child-mind-institute-detect-sleep-states/discussion/440697 for more info.
\nYesterday, the competition hosts completed the data update as well as performed the leadeabord rescoring. You may need to retrain your model with the updated data to recover previous model performance, to avoid the effects described in https://www.kaggle.com/competitions/child-mind-institute-detect-sleep-states/discussion/441415 .
\nI hope it is helpful.
