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.

 It is summer time.

Ok, then.  Anybody have a suggestion for a general term for which
daylight saving and summer time are special instances?

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

 The Danish version talks about UTC, which is cute since in Denmark
 legal time is still mean solar time at the Copenhagen Observatory,

How does this work in practice?  Lots of web hits show Copenhagen in
the Central European Timezone, one hour ahead of Greenwich (ignoring
the whole summer time issue).  Its longitude appears to be 12.66
degrees east, or 50 minutes ahead.

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.

Doesn't Universal hint at the join of the SI second and Solar Time?

Oftentimes labels of X are put on things to give the impression of
a good bit more X than is actually at hand.

I suspect that Universal in UTC has the same lineage as democratic
in The Democratic Republic of Congo.

UTCs proper name would have been ITC, International Time Coordinated.

 Indeed, it is sometimes used to mean that even in the summer.  There was
 some confusion in my company last year about a teleconference scheduled in
 GMT which turned out to actually refer to British Summer Time.

Microsoft *spit* Outlook calendar management talks about GMT Daylight

appointment request from my boss with so do you want to meet at 10:00 GMT
