sorry for this trivial question about dates

But you may not be quite right in saying that the whole EU changes
clocks simultaneously. Brussels has, I agree, said 01:00 UTC; but I
think that the corresponding UK document may put the changes at 01:00
GMT - which can differ by up to 0.9 seconds.

UK law 1997:
<http://webexhibits.org/daylightsaving/uk.html>

EU law 2000:
<http://webexhibits.org/daylightsaving/eu.html>

Both say GMT !

They are, I believe, American; they are certainly not authoritative; but
they may be right.

<http://www.dti.gov.uk/er/sumtimetb.htm>, updated 20 March 2003, uses

lexapi!prod!CELEXnumdoc&lg=EN&numdoc=32000L0084&mo del=guichett> of 19
January 2001 which uses GMT. Those are authoritative.

But <http://www.merlyn.demon.co.uk/uksumtim.htm> has noted that
"Statements about the EU rules are derived from the English version
(which uses GMT; others do not)."

Such laws or regulations should refer to UTC, IMHO.

On the other hand, is the exactness of legal local time within one
second that important?

Any serious scientific time measurement on that level of tolerance
should be in UTC.

Imagine a police officer saying: "You are not using your headlights at
night and it night since is 0.9 seconds". That would be zero-tolerance !
