IT is time to have a look at time for fun.

• The science of timekeeping is known as horology.

• A nanosecond is one billionth of a second, and a picosecond is one trillionth or 0.000 000 000 001 of a second.

• Planck time is the shortest known time span. It is the time it takes for light to travel a Planck length or 1.616199x10-35 metres in vacuum.

• Contrary to popular belief, a light year is not a unit of time, but a unit of distance. The International Astronomical Union defines a light year as the distance light travels in vacuum in one Julian year. In astronomy, a Julian year corresponds to exactly 365.25 days.

• A “jiffy” is usually used to indicate a very short period of time, but it is formally defined in the fields of physics and chemistry as the time required for light to travel a centimetre. Also known as a light centimetre, a jiffy is equal to about 33.3564 picoseconds.

• Eschatology is a sub-field of a variety of disciplines including theology, philosophy and physics that deals with the end of the world or end of time..

• According to the Oxford English Dictionary, time is the most frequently used noun in the English language, while year is the third most frequently used noun. Person is the second most used noun.

• The sun’s light reaches the surface of the Earth about eight minutes after it has left the surface of the sun.

• Sidereal time measures time according to the position of stars in the sky. A sidereal day is the time it takes for a specific star to reach the same position in the sky. It is a few minutes shorter than a mean day, spanning 23 hours, 56 minutes and about four seconds
