but what about the night, when the clocks a set back from summer time (CEST) to winter time (CET) and we have two times the hour between 02:00 and 03:00 ??

In environments where events have to be registered correctly (e.g. police) the
terminology 02:01A for the first hour, and 02:01B for the second hour is used.
And such data can't be stored to type TIMESTAMP, right?
