| The Geochron simultaneously shows time
and displays the extent of daylight and
darkness throughout the world. The only
instrument of its kind, the Smithsonian
Institute calls it the last significant
contribution in time keeping. A highly
accurate wall map and world time clock,
it is often used to decorate an office,
boardroom or reception area. |
|
Specifically, the Geochron shows
the following:
-
WORLD TIME: There are 34
local world time zones and Geochron
shows them all and eliminates the
confusion caused by time conversation
factors, the International Dateline,
and the question of A.M. or P.M. involved
in the use of a 12 hour clock. With
Geochron, the entire world time situation
is seen at a glance.
-
DATE AND DAY OF THE WEEK:
Days of the week and dates of the
month throughout the world are clearly
indicated. Since the map moves from
left to right, the International Dateline
crosses the frame once each day. The
days, date and month observed on either
side of the Dateline are displayed
via indicators mounted at the Geochron's
bottom.
- DAY AND NIGHT: Geochron illustrates
where it's day and where it's night.
See sunrise, high noon and sunset as
they happen around the world. Ever-changing
areas of day and night make a complete
cycle every 24 hours and gradually
changes shape with the seasons. What's
more, the Geochron can be moved forward
or backward in time showing the time
of sunrise and sunset in any given
place and date, past or future -- perfect
for mystery writers and travel planners.

- SEASONS: As the seasons change,
the light pattern will reflect this
throughout a year. See the pictures
below where the clock is showing; the
Summer Solstice; the Winter Solstice
and The Spring and Autumn Equinoxes!
