To make things more "normal" to humans, who seem to like "Noon" to be
when the sun is "straight up", the four "time zones" "Eastern",
"Central", "Mountain", and "Pacific" were established and the standard
time in these zones, "adjusted" so as to be an hour different east to
west, keeping "noon" close to where it should occur in the day as the
sun passed overhead.


They conveniently forgot to mention it was a Canadian, Sandford Fleming,
who invented standard time.


Wow, a Canuck invented time!

LMFAO!

Egypt,Sumer etc . all had calendars and sundials . Nothing unusual
here ; standard time was imperative/mandatory/necessary for
navigational purposes --hence England and GMT . BTW, what type of
clocks are good enough for space travel ?

Standard time was invented for railroads, celestial navigation only
requires GMT, as you can guess your longitude by where the sun is
in relation to where it would be if you were at the prime meridian
(GMT).

You can guess your latitude by where the sun is in relation to where it would
be at the equator, e.g. noon would be directly overhead.

For the USA it used to be Bulova Accutrons
in the Spacecraft; and Omega Speedmasters
on the Wrists of the Astronauts.

you can get a nice cesium clock that'll fit in a couple rack spaces
these days. I have a wild quartz clock that has kept perfect time for 23
years. It has a Westminster chime that synchronizes perfectly with the
Beeb's Five Pips. My Casio goes beepbeep right in the middle.



All times are GMT +1. The time now is 07:51 PM.
