Time - Temporal Measurement

Temporal Measurement

Temporal measurement, or chronometry, takes two distinct period forms: the calendar, a mathematical abstraction for calculating extensive periods of time, and the clock, a physical mechanism that counts the ongoing passage of time. In day-to-day life, the clock is consulted for periods less than a day, the calendar, for periods longer than a day. Increasingly, personal electronic devices display both calendars and clocks simultaneously. The number (as on a clock dial or calendar) that marks the occurrence of a specified event as to hour or date is obtained by counting from a fiducial epoch – a central reference point.

Famous quotes containing the words temporal and/or measurement:

    When once a certain class of people has been placed by the temporal and spiritual authorities outside the ranks of those whose life has value, then nothing comes more naturally to men than murder.
    Simone Weil (1909–1943)

    That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.
    John Dos Passos (1896–1970)
