More exactly, the mean solar day is 86.400 002 ks due to tidal braking, and increasing at the rate of approximately 2 ms/century; to correct for this time standards like UTC use leap seconds with the interval described as "a day" on them being most often 86.4 ks exactly by definition but occasionally one second more or less so that every day ...
10 microseconds (μs) – cycle time for frequency 100 kHz, radio wavelength 3 km. 18 microseconds – net amount per year that the length of the day lengthens, largely due to tidal acceleration. [3] 20.8 microseconds – sampling interval for digital audio with 48,000 samples/s. 22.7 microseconds – sampling interval for CD audio (44,100 ...
Earth-based: the day is based on the time it takes for the Earth to rotate on its own axis, as observed on a sundial [citation needed]. Units originally derived from this base include the week (seven days), and the fortnight (14 days). Subdivisions of the day include the hour (1/24 of a day), which is further subdivided into minutes and seconds ...
Such alternative units did not gain any notable acceptance. In China, during the Song dynasty, a day was divided into smaller units, called kè . One kè was usually defined as 1 ⁄ 100 of a day until 1628, though there were short periods before then where days had 96, 108 or 120 kè. [7] A kè is about 14.4 minutes, or 14 minutes 24 seconds.
So before you, perhaps, head back to the office tomorrow, it’s a good day to enjoy some college football—or, if you’re going a bit stir crazy, get out one last time.
A millisecond (from milli-and second; symbol: ms) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10 −3 or 1 / 1000) of a second [1] [2] or 1000 microseconds. A millisecond is to one second, as one second is to approximately 16.67 minutes.

A sidereal rotation is the time it takes the Earth to make one revolution with rotation to the stars, approximately 23 hours 56 minutes 4 seconds. A mean solar day is about 3 minutes 56 seconds longer than a mean sidereal day, or 1 ⁄ 366 more than a mean sidereal day.
