Hexadecimal time
Encyclopedia : H : HE : HEX : Hexadecimal time
The hexadecimal time format divides the day either into sixteen or into twice sixteen equal hexadecimal hours.
There are always 256 hexadecimal minutes in a hexadecimal hour and 16 hexadecimal seconds in a hexadecimal minute.
The sixteen hours a day format
The hexadecimal 16H/day time format was first proposed by the Swedish-American engineer John W. Nystrom in 1863.In 1997, the American Mark Vincent Rogers of Intuitor, unaware of Nystrom's system, proposed a similar system of hexadecimal time and implemented it in JavaScript as the Hexclock. Mr Rogers’s proposal uses the hexadecimal digit system of 0-9 and A-F. A day is unity, or 1, and any fraction thereof can be shown with digits to the right of the hexadecimal point. Example: Noon = 0.80000 (hex)day. However, for convenience, especially outside the technical fields: the first digit to the right of the point refers to the hexhours; the next two, the hexminutes; and the fourth, the hexseconds.
The conversion from hexclock units of time is as follows:
| 1 hexhour | = | 675 s | × | 8 | = | 1 H 30 | |
| 1 hexminute | = | 675 s | ÷ | 32 | ≥ | 21.09 s | |
| 1 hexsecond | = | 675 s | ÷ | 512 | ≤ | 1.32 s | |
Intuitor-hextime is also denoted in a different fashion; rather than the conventional colon ( : ), the hexclock uses an underscore ( _ ) between hexhours and hexminutes. For example of use, noon in military time is 12:00, being the halfway point of the day. Translated to hextime, this would be 8_00, as half of the 16-hour set-up is eight hours (12/24 = 8/16). An other example: 8_A6 (≥ 12:58).
Thus, the conception of hexadecimal time, sixteen hours once a day, implicates only eight mean longitudinal great circles. Furthermore, the congruency to the familiar cardinal positions of all the three pointers at 3, 6, 9, 12 o'clock is deleted. By implementing sixteen hours as the entire day, the position of the pointers is identical to an analog 12-hour clock only once a day, at midnight.
The twice sixteen hours a day format
In 1989, M. Florencetime of Paris developed a "hexadecimal metric system" for weights and measures, including a time format with 2×16 H/day.
The conversion from the florencetime units is as follows:
| one hexadecimal hour | = | 675 s | × | 4 | = | 0 H 45 | |
| one hexadecimal minute | = | 675 s | ÷ | 64 | ≤ | 10.55 s | |
| one hexadecimal second | = | 675 s | ÷ | 1024 | ≥ | 0.659 s | |
Florencetime uses new hexadecimal digits, so-called "omni-literal digits" instead of the current hexadecimal digits (0-9 & A-F), the adopted standard since the middle of the 1950s. In his proposal, the sixteen hexadecimal digits are represented by consonants. The odd digits are represented by voiced consonants, the even digits (including zero) by voiceless consonants. The five vowels, "M" and "N", like the letters "L" and "R" are not used for digits, but the letter "H", like hexadecimal, can mean sixteen in special uses.
| Current standard : | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Omni-literal digits : | Q | B | P | V | F | Z | S | D | T | J | C | G | K | Y | X | W |
Even though its inventor has always valued the possiblity of being able to prove his inventorship, he decided to deliberately renounce his right to any industrial patent, so as not to not create new proprietary standards for any measuring instruments for all the new units of his "hexadecimal metric system" (SMH) or any other use. All applications, therefore, are free and gratis.
Next to the latitudes, Florencetime defined - in concordance with the hexadecimal time - also hexadecimal longitudes. The main meridian zero degree hexadecimal is identical to the meridian 11°15' East of Greenwich and this meridian also crosses the center of the city of Florence in Tuscany; therefore : "Florencetime". The meridian opposite to Florence ± H°QQ'q (= 168°45' W of Greenwich) passes in the middle of Bering Strait, eastern to Diomede Islands; see this [map]. In the newly proposed hexadecimal geographic coordinate system, there are 32 hexadecimal main meridians spanned from pole to pole. The meridian of Greenwich is the first one western, as the meridian of Delphi ([map]) is the first one eastern of Florence.
In Europe, the Florence meridian (± Q°QQ'q), coming from North Pole by western coast of Svalbard, traverses Norway, Sweden, Denmark, Germany, Austria and Italy. In Africa, it passes to Tunisia, Libya, even to Algeria in its extremely south-east, then Niger, Nigeria, Cameroon and Equatorial Guinea. It crosses the equator with a continental point of confluence in Gabon ([map]) and leaves Africa at the northern coast of Congo-Brazzaville, going to South Pole in Antarctica by southern Atlantic Ocean and the Queen Maud Land.
Perpendicular to the longitudinal great circle Gabon – Fairway Rock islet, there is the longitudinal great circle Sumatra (in Asia) – Ecuador (in South America). This one crosses the equator of Earth even with two continental points of confluence, respectively at +T°QQ'q (= 101°15' E Greenwich [link]) and at -T°QQ'q (= 78°45' W of Greenwich [link]).
The meridian, zero degree hexadecimal, of Florence defines and postulates also a new Universal Time, the so-called : UTC.F = UTC(.G) + 2700 seconds.
