This should be taken as a hint to people in other countries with access to
suitable libraries to write the legislative histories of summer time in
those countries (of course coordinating via this list to avoid
duplication) ....

The directives I have (First through Fifth) all use "summertime".

The European directives (at least the First to Fifth) all use GMT when
stating the start time.  The legal time in the UK outside of summer time
is definitely GMT, not UTC; see Lord Tanlaw's speech at

columns 964 to 976).
