Ke A second system subdivided the day into 100 equal parts, ke, each of which equalling 14.4 minutes or a familiar rough quarter of a standard Western hour. This was valid for centuries, making the Chinese first to apply decimal time - long before the French revolution. However, because 100 could not be divided equally into the 12 “hours”, the system was changed to variously 96, 108, and 120 ke in a day. During the Qing Dynasty, the number was officially settled at 96, making each ke exactly a quarter of a Western hour. Today, ke is often used to refer to a quarter of an hour. figbranch.com/index2.php?option=com_content&do_pdf=1&id=14
