Yes, one interesting detail here is the use of the word "klokketiden"
which literally means "(Church-)Bell-Time", but which most people
would understand as "clock-time"

This word first appears in 1946 in the first law to introduce
DST in Denmark, and _presumably_, but we cannot know for sure,
this was meant to distinguish "clock time" from "solar time":

I have only ever seen it once, and that was my own doing:

When we ran into this, We tried to see if we could fit
the 'A/B' designator on the receipt printed by the automatic
gas-pumps without using another line of text.

We couldn't and since we could not have a special print format
during that one hour a day, compliance would have used 138km more
paper per year.
