Even worse with transit in Vienna/Austria where if you buy tickets in advance for a specific day or date range they seem to take your local time into account if those tickets are bought while in another timezone. That's for tickets where time shouldn't even matter because they are for full days (from midnight to midnight).

If you're in Pacific time and you buy the ticket for a date in the future (let's say June 1st) before 3pm your local time everything works fine. But if you buy the same ticket for June 1st after 3pm Pacific local time (which is already the next day in Vienna) the ticket that you're buying isn't for June 1st but actually for June 2nd (only visible once you receive the confirmation).

So apparently they're somehow translating between timezones for the displayed dates, although that doesn't make sense: If I buy a ticket for June 1st on Vienna public transport I don't care what my local time is. Even if I'm in California while buying that ticket I still want it to be valid on June 1st instead of June 2nd.
