Official U.S. Time
Accurate to within 1 second. Pick a time zone in the the United States or
its territories and the official US government time is displayed in large,
easy-to-read numerals, along with the coordinated universal time and a world
map displaying where the sun is currently shining. Also available are Time
Exhibits, that explain the histories of Daylight Savings Time; of calendars;
of clocks and watches; of timekeeping, and more. Provided cooperatively by
the National Institute of Standards and Technology Time and Frequency
Division and the U.S. Naval Observatory Time Services Department. There is a
link to a page with international time zones.

TimeTicker
A graphic view of the current time around the world. Click on the location
on the map (or use the scrollable list), and TimeTicker brings you back the
precise time and date along with the major cities for that zone, all
packaged in a very flashy format. The Shockwave plug-in is required.

Universal Photoperiod Calendar
This site provides a calculator that displays the day length, times for
sunrise and sunset, the height angle of the sun at noon, the declination,
the time compared to Greenwich Mean Time (UMT), and the latitude and
longitude for locations around the world. User may choose a location from a
drop down menu of selected cities or enter a latitude and longitude of their
choice for the calculations and may select daylight savings time or standard
time. There are links to other astronomical calculators and one to
definitions of sun rise and set, moon rise and set, and twilight. A version
of the calculator (for Excel) may be downloaded

Walk Through Time
Presents a historic view of the evolution of time measurement. The series
begins with ancient calendars and ends with the atomic age. It includes
information on and pictures of sun clocks and water clocks; mechanical
clocks and quartz clocks; and atomic beam clocks. The site also has
information on Greenwich Mean Time and world time zones. From the National
Institute of Standards and Technology (NIST) Physics Laboratory. You can
also check your computer\'s time clock.

See how it bulges out? Your eye and brain have balanced pairs of receptors for sensing movement - right/left, up/down, etc. Looking at movement in just one direction for a long time tires out one side of the pair and the imbalance causes you to see movement in the opposite direction.
