I don't know where you are, but in Denmark we gain close to 60
minutes extra daylight per day except for june/july, so we do
in fact "save the daylight for better use".

Well, local languages have their private definitions, in Denmark it
is summertime/wintertime.

Of course we use the same time as everybody else around us, (UTC +
1h/2h) but legally that is approx 14 minutes and 33 seconds wrong.

In all likelyhood, a lawyer would point to some international convention
or other about time (the meter convention, or some UN/ITU related thing)
which has superseeded the old law, but on the book, it is wrong.
