Abstract:
A time measurement device, comprising:a standard time measuring unit; and an elapsed time measuring unit including a split controlling unit and a time indicator hand; wherein the split controlling unit is adapted to temporarily suspend movement of the time indicator hand, during measurement of elapsed time, such that after a predetermined amount of time passes from the time that the time indicator hand is initially temporarily suspended, the split controlling unit automatically releases temporary suspension of the time indicator hand and causes the time indicator hand to be rapidly driven to a position indicating the elapsed time; the elapsed time measuring unit further comprising a first measuring unit that determines a position where the time indicator hand would be if its movement had not been temporarily suspended; a second measuring unit that determines a temporarily suspended position of the time indicator hand; a release unit that releases temporary suspension of the time indicator hand after the predetermined amount of time; a comparator that compares the position of the time indicator hand determined by the first measuring unit and the position of the time indicator hand determined by the second measuring unit; and a time-indicator-hand driving unit that rapidly drives the time indicator hand based on the comparison result generated by the comparator, when the release unit releases temporary suspension of the time indicator hand.
