- Hexadecimal time
**Hexadecimal time**is the representation of thetime ofday as ahexadecimal number in the interval [0,1).The day is divided in

**10**(sixteen) hexadecimal hours, each hour in**100**(two hundred fifty-six) hexadecimal minutes and each minute in**10**(sixteen) hexadecimal seconds.This time format was first proposed by the Swedish-American engineer

John W. Nystrom in 1863. In 1997, the American Mark Vincent Rogers ofIntuitor , unaware of Nystrom's system, proposed a similar system of hexadecimal time and implemented it inJavaScript as the Hexclock.A day is unity, or

**1**, and any fraction thereof can be shown with digits to the right of the hexadecimal separator. So the day begins at midnight with**.0000**and one hexadecimal second after midnight is**.0001**. Noon is**.8000**(one half), one hexadecimal second before was**.7FFF**and one hexadecimal second before next midnight will be**.FFFF**.Intuitor-hextime may also be formatted with an underscore separating hexadecimal hours, minutes and seconds. For example:

01:30:00 =

**1_00_0**=**.1000**( 1.5÷24 = 1÷16 =**0.1**) 12:00:00 =**8_00_0**=**.8000**( 12÷24 = 8÷16 =**0.8**) 22:30:00 =**F_00_0**=**.F000**( 22.5÷24 = 15÷16 =**0.F**)**ee also***
