  • as basis a physical model, which must be realized for technical application sufficient exactly (z. B. by Zeitsignale or atomic clocks), and an exactly specified zero point.
  • The most important time scale is that one the world time (UT1, UTC), which is connected with the earth rotation over the sidereal time. Their unit is the atomic-physically defined SI second and the annual course movement of the earth.
  • The contrast to a time scale of thisstrict sense is relative time measurement - z. B. with a stop watch - where the zero point can be arbitrary because of the bare measurement of a time difference. In the everyday life this meaning of „time is frequent and can the respective purpose good “are adapted.

qualitative time scales

are to be preferred however if the exact „yardstick is less important “than the sequence of the regarded phenomena. Such time scales would list events or sections, which took place at a certain time, in their orderup, the exact length of time between them is however less important than the mutual allocation of different event rows.

Time “is understood as a kind distance between two or more events , the time scale is a systematic consequence of these events here andsecures its connection. Depending upon purpose of a time scale, it avails itself of an appropriate time interval between the events, in order to illustrate these. Like that for example a representation of earth ages would not be helpful in the unit second the purpose of the illustration.

Sometimes in the science of history can be worked without strict time measure, if z. B. instead of the years the sequence of dynasties the time frameworks determines.
