A thoroughly enjoyable day as usual :-)
Thanks to everyone involved.

Thanks Jon [it was a great day] and for my Ewell AS stand topping you
pics :-).

Can I suggest you shift the 'dot' from after your URL - it stops i
being 'hot' linked eg has to be cut 'n pasted to work.

Better to suggest bracketing it with < > or <URL: > which will also
cause good newsreaders to recognise it as an entity even if wrapping
splits it onto more than one line.

For minor general interest : 2005-12-31 23:59:60 UTC will occur;
sometime during it, the UK civil year number will change.

Oops. I usually do that, but forgot and then made things worse by using
"correct" punctuation :-) My own reader (Turnpike) had no problems but I
gather some do.

Is that because of a leap second?

What else could cause it? 23:59:60 is necessarily a positive leap
second, and absence-of-23:59:59 is necessarily a negative one. If there
is no leap second, the GMT change (and I believe the UK legally uses
GMT, in spite of UTC time signals) must be either in the first second of
the new UTC year, 00:00:00, or in the last of the previous, 23:59:59.

There is a news story at http://www.spacedaily.com/news/time-05d.html giving
further details of the leap second. In the long term they will occur more
and more and more often as Earth's disproportionately large moon slows its
rotation further until, like Pluto's, Earth's own rotation is locked to its
moon's orbit.

This is getting a bit off topic, but I'm fairly sure that won't happen -
the Sun will have become a red giant by then and it's not certain that
Earth will survive.
It's a bit depressing that most of the web sites that come up in a
search for "moon" and "recession" are either pro- or anti-creationist.

Please put responses after trimmed quotes, as called for in the
newsgroup FAQ, in UK News guidelines (e.g. "Configuring your news reader
to post to uk.*" section 3.1), and in Usenet guidelines.

You can also read about Leap Seconds via the sig below, repeated from
the previous article.

It is a mistake to blame only the Moon for the change in the length of
the day; the tidal effect of the Sun is at much the same frequency as
that of the Moon, and only moderately smaller in amplitude: consider
spring & neap tides.

Tidal drag slows the Earth by ~ 7 ms/yr/yr, and would imply increasing
frequency of leap seconds in the long term (when locked, we'd need many
thousands of them per day AFAICS); but in the much shorter term it seems
moderately likely that they will be abandoned in favour of some other
scheme. So enjoy the coming one; it might just possibly be the last.
