    How did you get to that epoch? I haven’t seen any images of this happening earlier than 2003, so the overflow must have happened late last year or early this year, and whatever week 0 is is some time around 2002/2003. That would also fit with your comment that they were introduced in the early 2000s.

    Maybe they just didn’t expect the trains to last 20 years 😄

      undefined> 20 y

      Well, I did shown_date-1024 weeks=epoch. Your explanation sounds correct, though.

      The only thing is, I’ve seen 2003 date before 2023 in random trains. Could also be a weird glitch when time sync fails or something.

        It could be that the epoch is the start of 2003, so any train with a reset week counter shows 2003, and now they all do since the counter has overflowed late last year.

        The fact that they use a week counter in general is something I remember from someone familiar with the onboard computer system, but I don’t remember how it’s set up specifically unfortunately.
