A world clock is a clock which displays the time for various cities around the world.
The display can take various forms:
- The clock face can incorporate multiple round analogue clocks with moving hands or multiple digital clocks with numeric readouts, with each clock being labelled with the name of a major city or time zone in the world.
- It could also be a picture map of the world with embedded analog or digital time-displays.
- A moving circular map of the world, rotating inside a stationary 24 hour dial ring. Alternatively, the disc can be stationary and the ring moving.
- Light projection onto a map representing daytime, used in the Geochron, a brand of a particular form or world clock.
There are also worldtime watches, both wrist watches and pocket watches. Sometime manufacturers of timekeepers erroneously apply the worldtime label to instruments that merely indicate time for two or a few time zones, but the term should be used only for timepieces that indicate time for all major time zones of the globe.
Famous quotes containing the words world and/or clock:
“No man, however benevolent, liberal, and wise, can use a large fortune so that it will do half as much good in the world as it would if it were divided into moderate sums and in the hands of workmen who had earned it by industry and frugality. The piling up of estates often does great and conspicuous good.... But no man does with accumulated wealth so much good as the same amount would do in many hands.”
—Rutherford Birchard Hayes (1822–1893)
“They’ll take suggestion as a cat laps milk;
They’ll tell the clock to any business that
We say befits the hour.”
—William Shakespeare (1564–1616)
