Hexadecimal time is the representation of the time of day as a hexadecimal number in the interval [0,1] or [0,2], regulary multipied by a multiple of 16.

The day is divided in 0x10 (sixteen) or 0x20 (twice sixteen) hexadecimal hours, each hour in 0x100 hexadecimal minutes (i.e. two hundred fifty-six base ten) and each minute in 0x10 (sixteen) hexadecimal seconds.

This time format was first proposed by the Swedish-American engineer John W. Nystrom in 1863. In the year 1991 a twice sixteen hour system was proposed in Europe. In 1997, the American Mark Vincent Rogers of Intuitor, unaware of Nystrom's system, reinvented a once sixteen hours system of hexadecimal time and implemented it in JavaScript as the Hexclock. In his system a day is unity, or 1, and any fraction thereof can be shown with digits to the right of the hexadecimal separator. So, according to Intuitor, the day begins at midnight with .0000 and one hexadecimal second after midnight is .0001. Noon, par example, is .8000 (one half). John W. Nystrom (1825-1885) was a Swedish-American engineer, living in Philadelphia, United States. ... Intuitor is a website that is devoted to educating people on physics. ...
