Yeah, 1 realization I made a long time ago was a day could have 25 hours or 23 hours. And a clever system having a timeline would show, e.g. in the Central European timezone:

1 AM, 2 AM (CET), 2 AM (CEST), 3 AM, 4 AM...

1 AM, 2 AM (CEST), 4 AM (CET), 5 AM, ...

According to a commenter above, the norwegian station of Troll[0] is on UCT in summer time but UTC+2 in winter time, so its "day" can have 22~26h.

Then there's the possibility of timezones straight moving around which can make entire days replay or disappear e.g. in Samoa there is no 2011-12-30, the day literally doesn't exist, Samoa local calendar goes straight 2011-12-29 to 2011-12-31, because at midnight the country switched from UTC-11:00 to UTC+13:00.

There's an intriguing way that railways handle the transition around here (central Europe): one way, trains stop in stations for an hour, the other, they all get an +1 hr delay at next station.

Sorry but do you have a citation on that? Never seen anything like that in Europe.

Not original commenter, but basically he's right, according to the German Rail (in German): https://www.deutschebahn.com/pr-hamburg-de/hintergrund/theme...

If a night loses 1 hour, the train stops for less time at the scheduled stops, or arrives with a delay. If the night gains an hour, the train waits somewhere for an hour. Which sounds like a painful thing, having to travel (or wait) an extra hour because of clocks.

Interestingly if the night loses an hour, the trains are automatically an hour behind schedule...

Beeing an hour behind schedule is not that uncommon.....

Other than [OWNRESEARCH], i.e. experienced that a few times? Not really, no.

Its like this in germany
