Problems with certain times occuring twice (or not at all) on night of daylight saving time to standard time transition
In most of Europe, when the clocks are set from daylight saving time to standard time, at 3 AM the clocks are set back to 2 AM. Thus, a time like 2:29 happens twice in that night. In spring, the clocks go from 1:59 to 3 AM straight. Thus, 2:29 does not happen at all.
Imagine a plane leaving at 2:29 AM from a certain place. When does it actually leave on those two nights?

As for trains, in Sweden, trains at the end of DST will stop at the first station possible after 1:00 UTC (the instant the clocks are put back). As to the start of DST, all trains will instantaneously acquire a one hour delay at 1:00 UTC, and do their best to make up for the delay. If you take a night train at the start of DST, be prepared to have a one hour delay in the morning!

Answer 2
I found an interesting discussion on Airliners.net, and some of the forum posters seem to be working in the industry. To summarize some of the comments, it can be a source of major confusion both for passengers, crew members (forgetting about DST switching and arriving late), ground personnel (longer shifts than usual) and apparently entire airlines, especially for flights between destinations that do not switch to DST at the same time (or one of it doesn't use DST at all).
For most parts of the world, it would seem that domestic flights wouldn't be affected much, as these are rare in such ungodly hour, however the situation is different for international flights. There is a blog rant on this very issue for US flights.
