There are 31,557,600 seconds in a year.

Clocks made before 1660 had only one hand - an hour hand.
Perfect Timing - The second is defined as exactly 9,192,631,770 oscillations or cycles of the cesium atom's resonant frequency, replacing the old second that was defined in terms of the Earth's motions. The newest generation of the "Atomic Clock" is accurate to 30 billionths of a second a year. It is the most accurately measured physical quantity in science.
A chronometer is a watch or clock whose movement has been tested and certified to operate within a certain standard of accuracy.
The first battery-powered watch, the Hamilton Electric 500, was released in 1957 by the Hamilton Watch Company of Lancaster, Pennsylvania.

A leap year is a year in which one extra day has been inserted, or intercalated, at the end of February. A leap year consists of 366 days, whereas other years, called common years, have 365 days.
The vernal equinox is the time when the sun is directly above the Earth's equator, moving from the southern to the northern hemisphere. The mean time between two successive vernal equinoxes is called a tropical year–also known as a solar year–and is about 365.24 days long. Using a calendar with 365 days every year would result in a loss of 0.24 days, or almost six hours per year.
By adding a leap year approximately every fourth year, the difference between the calendar and the seasons can be reduced significantly, and the calendar will align with the seasons much more accurately.
ABOUT TIME ZONES:
Not all time zones are in one hour increments. Some countries use 30 minute offsets. When the time in Greenwich is 12:00 noon, it is 8:30am in Newfoundland and 9:30pm in Australia. In Nepal, however, they use a time offset in quarter hours, so the time there would be 5:45pm.
Talk about confusing... Prior to 1995, International Date Line split the country of Kiribati. The result was that the eastern part of Kiribati was a whole day and two hours behind the western part of the country where its capital is located.
