      Thank you Géza for the additional sources!

      Well, thanks, in fact I do have additional questions:

      • Is the 24 hours system generally used in Hungarian? More precisely:
        do "2 órakor" and "órakét" (at 2 hours) always mean 2 am or
        can they also mean 2 pm?
        (It is clear that "0 órakor" cannot mean noon.)

        And if these expressions may sometimes be ambiguous, how is am
        distinguished from pm?

      • Are there common Hungarian abbreviations for
              közép-európai téli idő  (central European winter time)
              közép-európai nyári idő (central European summer time)
        (for instance in travel schedules)? CLDR gives only the English
        forms CET and CEST, as far as I can see.

      Many thanks for your kind help.

      Michael Deckers.
