(I) In ancient time-measurement systems, including
those of both Egypt and China, daylight and night-time
were each given 12 hours. (II) This was convenient for
use with sundials, which are known from Egypt as early
as 1500 BC, although telling the time 'by the Sun'
probably predates the first humans. (III) However,
because the length of daylight and night-time varies with
the season, so did the length of the sundials. (IV) When
water clocks came into use, shortly after them, a conflict
between the two forms of measurement became
apparent. (V) In the 8th century AD, the Chinese began
to add primitive but a bit more sophisticated equipment
to water clocks.
