That makes sense to me, when documenting a fall back from 01:00 to 24:00 the previous day. Traditionally, midnight is in both adjacent days (or in neither day). Although the recent advent of computer-based clocks has promoted the currently-popular approach that midnight is part of the next day not the previous one, this approach surely hadn't taken hold in Hungary circa 1980. I installed the attached to try to cover your other comments; thanks.
