How can you trust the clock?
The train is using a week counter internally that overflowed. 17.11.2003 is exactly 1024 (2^(10)) weeks ago.
Damn you’re good
Ever heard of the 2048 bug? If no i suggest taking a look at the wikipedia page. I think it is a fun read
2038! I develop embedded systems and we’ve been testing for this for years now. There’s also a similar 2036 GPS bug
You mean the Year 2038 problem?
But this would mean the epoch here would be the 2 April 1984 or maybe the 1st, if you respect the time as well, which sounds a tiny bit random lol. But so would be to use a week counter in the first place :D Especially since those trains are from the early 2000s.
EDIT: Other times in 2003 are also possible apparently https://twitter.com/TAltgeld/status/1646386165006716928?ref_src=twsrc^tfw|twcamp^tweetembed|twterm^1646386165006716928|twgr^99a8805bbdf28d116a3a7037dc24347da978e819|twcon^s1_c10&ref_url=https%3A%2F%2Fwww.kreiszeitung.de%2Flokales%2Fbremen%2Fsorgt-fuer-spott-im-netz-geniale-loesung-der-db-der-zug-aus-der-vergangenheit-92212981.html
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.
Did you hit 88 mph?
Don’t think a German train can handle 1.21 gigawatts
Btw, thinking back to it, was that a nazi reference in that old movie?

You don’t seem to know “hidden” Nazi references. Over here, Nazi references are widely illegal (which is good), so they avoid that law by using increasingly obscure references, which are then banned as well.
The 8th letter of the alphabet is H, so 88 => HH => Heil Hitler. This is why over here, e.g. it’s not possible to register a license plate with an 88 in it.
Especially in Germany, these laws are so strict, that one guy was sued for displaying a pictogram of a stick man throwing a swastika into a waste bin, even though it was clearly meant as derogatory towards the swastika. They fixed this part of the law in the meantime.
Not sure why you’re being downvoted, I had no idea about 88->HH etc. Your seemed like a genuine question. Was the BTTF 88MPH a nazi reference?? Changes the entire series if it is.
First off, I assumed the original question was a troll. But, regardless. I’m not completely certain but, I doubt this was a known thing in 1985. I could be wrong but sometimes, things are just coincidences.
Deutsche Bahn making up 20 years of delays in one go. Now that’s efficiency
Old public clocks sometimes use the mains frequency as a clock signal to maintain correct time. At the end of the day, the power authority is supposed to adjust the signal slightly to make sure these clocks maintain the correct time.
So I built a device that analyzes mains power supply phase variance with microsecond resolution. It’s accurate enough that I can see the power authority turning on and off supplementary turbines to keeps the mains frequency correct.
That’s how I determine my level of trust in public clocks.
Well, that and maintaining sub-relativistic velocities relative to them. Which is pretty easy honestly. If you’re having problems with this, you’ve probably ceased to be biology or chemistry and started being physics. So you probably have more pressing concerns than keeping time!
Fellow vxjunkie, great to see on the other side
This is a train’s clock, though. And since these displays also show additional information, I guess there’s a bit more sophistication behind it.
Did you construct the analyzer yourself or can you buy that off shelf?
Ah, Deutsche Bahn. Gotta love it.
Ah, it’s about right give or take twenty years.
God I would love it if I was suddenly transported back to 2003 as my current self.
That’s a really old picture you got there ;)
Ah 2003, I remember it well.
I love German regional trains. This is a very common issue. Happens all the time.
