I am confused: there is no time scale specified in the Danish law
quoted. Do you mean that the reference in the footnote is supposed
to include the Danish text of a European Directive into Danish law,
without even explicitly quoting it?

No. The text of European Directive 2000/84/EC of 2001-01-19 is
issued by the EU in 22 languages, all with equal standing.
For the time scale determining the beginning and end of
summer time, these translations refer to:

-- Greenwich time in 4 cases (EL, ET, HU, LV)
-- Greenwich time with GMT in parentheses in 1 case (SV)
-- Greenwich mean time in 5 cases (EN, FI, LT, MT, SK)
-- Universal time in 5 cases (ES, FR, IT, PT, RO),
-- Universal time with GMT in parentheses in 1 case (PL),
-- World time (a term for UT according to the IAU) in 2 cases
(DE, NL),
-- World time with GMT in parentheses in 1 case (CS),
-- World time with UTC in parentheses in 1 case (DA), and
-- Universal coordinated time in just one case (SL).
(Thanks to Steve Allen who first did this comparison.)

In my opinion, this shows that the Directive does not
intend to prescribe the time scale. Or do you
think that it was the idea that the Danes and Slovenes
should follow UTC while the British follow GMT? Then certainly
the Welsh, Gaelic, Catalan, Basque,.. people would want to have
their own versions!
