I think you're out by a factor of 10. Would the Man On The Clapham Omnibus
be able to identify the solstice or equinox to within 14 days? Other than
knowing the "conventional" dates?

Already true.
For many months of the year, solar noon is closer to 1 PM, or even 1:30
PM, in a great many countries, an

Steve,
Some comments on your fine posting...

I found the Metrologia article interesting. I had heard
of 100 ms steps (leap tenth-seconds) but not the 50
ms steps.
Did you notice he appears to refer to a leap second

There seems to be persistent confusion on what is meant by the term
"leap hour". I understand it as a secular change to the various LCT offsets,
made either all at once (on 1 Jan 2600, say) or on an ad-lib basis.

I sure hope that the future of mankind's timekeeping systems doesn't
get decided by an Internet flame war between contending groups of
geeks...
As I see it, the dispute comes from the fact that people want two
different, irreconcilable types of "time", time of day (earth/solar
angle) and constant
