who came up with hours minutes and seconds
Hour The seasonal, temporal, or unequal hour was established in the ancient Near East as ​1⁄12 of the night or daytime. Such hours varied by season, latitude, and weather. It was subsequently divided into 60 minutes, each of 60 seconds. Its East Asian equivalent was the shi, which was ​1⁄12 of the apparent solar day; a similar system was eventually developed in Europe which measured its equal or equinoctial hour as ​1⁄24 of such days measured from noon to noon. The minor variations of this unit were eventually smoothed by making it ​1⁄24 of the mean solar day, based on the measure of the sun's transit along the celestial equator rather than along the ecliptic. This was finally abandoned due to the minor slowing caused by the Earth's tidal deceleration by the Moon.
