Sorry, but you're wrong. Article 2 requires the "summer-time period" to
begin on a certain date-time, and Article 1 defines the "summer-time
period" as putting the clocks forward by 60 minutes. Therefore every Member
State must put its clocks forward and back. (Except for the overseas
territories exempted in Article 6.)
