A hexadecimal clock-face (using the Florence meridian) Hexadecimal time is the representation of the time of day as a hexadecimal number in the interval [0, 1). The day is divided into 10 16 (16 10 ) hexadecimal hours, each hour into 100 16 (256 10 ) hexadecimal minutes, and each minute into 10 16 (16 10 ) hexadecimal seconds.
Sometimes in official records, decimal hours were divided into tenths, or décimes, instead of minutes. One décime is equal to 10 decimal minutes, which is nearly equal to a quarter-hour (15 minutes) in standard time. Thus, "five hours two décimes" equals 5.2 decimal hours, roughly 12:30 p.m. in standard time.
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
A second of arc, arcsecond (abbreviated as arcsec), or arc second, denoted by the symbol ″, [2] is a unit of angular measurement equal to 1 / 60 of a minute of arc, 1 / 3600 of a degree, [1] 1 / 1 296 000 of a turn, and π / 648 000 (about 1 / 206 264.8 ) of a radian.
It has since been set backward 8 times and forward 18 times. The farthest time from midnight was 17 minutes in 1991, and the closest is 89 seconds, set in January 2025. [5] The Clock was moved to 150 seconds (2 minutes, 30 seconds) in 2017, then forward to 2 minutes to midnight in 2018, and left unchanged in 2019. [6]
For medieval commoners the main marker of the passage of time was the call to prayer at intervals throughout the day. The earliest reference found to the moment is from the 8th century writings of the Venerable Bede , [ 5 ] who describes the system as 1 solar hour = 4 puncta = 5 lunar puncta [ 6 ] [ 7 ] = 10 minuta = 15 partes = 40 momenta .
In a digitally modulated signal or a line code, symbol rate, modulation rate or baud rate is the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time. The symbol rate is measured in baud (Bd) or symbols per second. In the case of a line code, the symbol rate is the pulse rate in pulses ...
Minute is a unit of time defined as equal to 60 seconds. [1] One hour contains 60 minutes. [2] Although not a unit in the International System of Units (SI), the minute is accepted for use in the SI. [1] The SI symbol for minutes is min (without a dot). The prime symbol ′ is also sometimes used informally to denote minutes. [3]
