         The Percentage Metric Time Clock gives the percentage of the day that has elapsed thus far. One day consists of 100 Percentage Metric Hours. One Percentage Metric Hour has 100 Percentage Metric Minutes (PMM) and One Percentage Metric Minute has 100 Percentage Metric Seconds (PMS), i.e., One PMM = 0.01 PMH and One PMS = 0.0001 PMH. One conventional hour = 4.167 Percentage Metric Hours and One Percentage Metric Hour (PMH)= 0.24 conventional hour, i.e., one PMH = almost a quarter conventional hour, i.e., one PMH = 14 conventional minutes plus 24 conventional seconds. One Percentage Metric Minute = 8.64 conventional seconds.

         Current World Standard Percentage Metric Time gives the current local Percentage Metric Time for Greenwich, England. This World Standard Percentage Metric Time is therefore comparable to the current Greenwich Mean Time and Universal Time that may be used as a reference point to insure communicating the exact same instant in time regardless of where a person is on earth. This means that the current World Standard Percentage Metric Time may be used for ease of communicating time around the world, e.g., for business purposes.

24 Hours?

         "The custom of dividing each day into 24 parts seems to have originated with the ancient Egyptians in about 3500 B.C.. They divided daylight and darkness into periods of 12 hours each. But this meant that the length of each hour changed during the year as the nights lengthened and shortened. It was Babylonian astronomers who, in about 300 B.C., adopted the now universal practice of making all 24 hours equal in length, regardless of when the sun rose or set. In Europe, however, equal hours did not become standard until about A.D. 1350, some 70 years after the introduction of mechanical clocks."
From Reader's Digest Book of Facts 1987.
