Came here looking for a comment suggesting these discrepancies. I was not disappointed. See also: “Falsehoods programmers believe about time” https://infiniteundo.com/post/25326999628/falsehoods-program...
Can anyone recommend a book that discusses in depth all the peculiarities of timekeeping, time zones, historical efforts for measuring time, etc.? I would love to read something like that and I feel that there are many stories to be told.
It’s a long post, not a book but still a great resource on this topic:
