Today is December 21st and it is the winter solstice. That means it is
the shortest day of the year. Now I will get 1-2 minutes of daylight
each day to play those bums and street players at Washington Square
Park in New York City. Maybe I can convince them to now give me an
extra 1-2 minutes on my clock.
I really hope I get bus service today. All those employees were on
strike and I had to walk to yesterday today in the freezing cold. Maybe
they all went to play chess somewhere.

You and I understand him the same way, but I was making the point that
what was said was not the same as what was meant. Others may profit
from such an example.
I don't know enough astronomy to calculate length of day by myself.
But let me point out that, due to westward rotation, the latest sunrise
and the earliest sunset do not necessarily occur on the same calendar
day. In addition, the solstice is almost certain to occur on different
dates in different time zones. Possibly in certain time zones the date
of the solstice and the civil day with the shortest daylight are
different by a second or two.
Unfortunately Google only maintains sci.astronomy as an archive so I
cannot crosspost there to obtain further discussion.

The latest sunrise and the earliest sunset are a week or two apart - this is
because the Earth's orbital velocity changes as its distance from the sun
varies, whereas its rotational velocity is fairly constant through the year,
leading to the actual noon measured at Greenwich on the equinox being some
minutes away from the "mean" greenwich noon used by GMT and approximated by
UTC.

I think by day he means daylight hours, the solstice does indeed ks
the day with the shortest daylight hours.

In April, when we change from Standard Time to Daylight Time, one day
has only 23 hours.
The Leap Second is not guaranteed in any year. The time goes
officially from 23:59:59 to 23:59:60 and then back to 0:00:00.

Hello
I though all days have the same amount of seconds being the only
exception the last day of the year (or the first one in next year)
which has an aditional second.
Due to the influence of the moon earth is rotating slowly, did you
know?

The last minute in June or December can have 59, 60 or 61 seconds, but the
first minute in January can only have 60 seconds. The last minute of this
December will have 61 seconds - this will be the first leap second for
several years.

Hello John, ...
But that depends on geografical situation (respect to GMT), there are
places where 2005 last day will have 61 sec and places where 2006 first
day will have an aditional second (as Spain).
