Not any more - it's now 01:00.  The reason for this is harmonization
across europe.  Regardless of which actual zone, the change now occurs at
the same instant, keeping the time difference between zones constant,
(thereby abolishing the maze of footnotes in rail/air timetables to
do with the odd behaviour of cross-boarder trains/planes on the days
when the times changed).  See /usr/src/share/zoneinfo/europe.

Hence the answer to the original poster's question is that you can't win:
there is no one hour to avoid, since the change occurs at different
times in different places.
