Hexadecimal time

from Wikipedia, the free encyclopedia

The hexadecimal time is a representation of the time as a hexadecimal number in the interval [0.1). This numerical value indicates directly which part of the day has already passed, i.e. identifies midnight with .0000 , noon with .8000 (one half) and the moment before the next midnight with , FFFF ( period of fifteen ; what in the decimal system is the Period of nine is).

Such a time calculation with sixteen hours per day was proposed as early as 1863 by the Swedish-American engineer John W. Nystrom (1825–1885). In the practice of time measurement , this representation could not prevail over the sexagesimal system in everyday life and the decimal time in science ( Julian date ).

When measuring time with hexadecimal time, the day is divided into 10 hex (= sixteen) hexadecimal hours. Each of these hours then has 100 hex (= two hundred and fifty- six) hexadecimal minutes and each hexadecimal minute has 10 hex (= sixteen) hexadecimal seconds. These terms facilitate the comparison with the traditional time, but should not hide the fact that it is simply the first to fourth decimal places of a hexadecimal number.

01:30:00 = , 1000 (1.5 ÷ 24 = 1 ÷ 16 = 0.1 )
12:00:00 = , 8000 (12 ÷ 24 = 8 ÷ 16 = 0.8 )
22:30:00 = , F000 (22.5 ÷ 24 = 15 ÷ 16 = 0, F )

1 day = 1 . 0 0 0 0 hex = 6th 5 . 5 3 6th hexsec = 24 hours
1 hexadecimal hour = 1 0 0 0 hex = 4th . 0 9 6th hexsec = 1 h 30 min
1 hexadecimal maxim = 1 0 0 hex = 2 5 6th hexsec = 5 min 37.5 sec
1 hexadecimal minute = 1 0 hex = 1 6th hexsec ≈ 21.09 sec
1 hexadecimal second = 1 hex = 1 hexsec ≈ 1.32 sec
