Ten seconds (one sixth of a minute) minute: 60 s: hectosecond: 100 s: milliday: 1/1000 d (0.001 d) 1.44 minutes, or 86.4 seconds. Also marketed as a ".beat" by the Swatch corporation. moment: 1/40 solar hour (90 s on average) Medieval unit of time used by astronomers to compute astronomical movements, length varies with the season.

3.6 ks: The length of one hour (h), the time for the minute hand of a clock to cycle once around the face, approximately 1/24 of one mean solar day. 7.2 ks (2 h): The typical length of feature films 35.73 ks: the rotational period of planet Jupiter, fastest planet to rotate 38.0196 ks: rotational period of Saturn, second shortest rotational period
For others, there would be 50 decimal minutes per decimal hour, and 100 decimal seconds per decimal minute. His new hours, minutes, and seconds would thus be more similar to the old units. [14] C.A. Prieur (of the Côte-d'Or), read at the National Convention on Ventôse 11, year III (March 1, 1795):
The time kept by a sundial varies by time of year, meaning that seconds, minutes and every other division of time is a different duration at different times of the year. The time of day measured with mean time versus apparent time may differ by as much as 15 minutes, but a single day differs from the next by only a small amount; 15 minutes is a ...
(The leading zero is more commonly used with the 24-hour notation; especially in computer applications because it can help to maintain column alignment in tables and correct sorting order, and also because it helps to highlight the 24-hour character of the given time.) Times of day ending in :00 minutes may be pronounced as the numbered hour ...
Whether written months are identified by name, by number (1–12), or by Roman numeral (I-XII). Whether the 24-hour clock, 12-hour clock, or 6-hour clock is used. Whether the minutes (or fraction of an hour) after the previous hour or until the following hour is used in spoken language.
Today's state the hours, minutes, and seconds. In a strict sexagesimal system these three would be expressed in a single, three-digit sexagesimal number: h,m,s with values on each of the three letters of 0-59; that is, hours up to 60, minutes up to 60, and seconds up to 60. Because integer numbers are expressed as sums, in this case
