GTFS requires you to put all the stoptimes in the same time-zone, each
agency has one timezone (and Transit only accepts one agency time_zone per
Trips across different timezones are then handled by the time_zone in
stops.txt, so you can convert to local-time.
Of-course there are probably still a ton of caveats here, even for just the
Netherlands on the nights of the DST switch.
Also Google has data for the Russian Railways (GTFS? HAFAS? we dont know
even for DB) allowing you to route Scotland->Vladivostok effortlessly
