PROBLEM TO BE SOLVED: To manage plural different times via a simple constitution of a time management device. SOLUTION: In a stop mode, the difference is calculated between the time shot by the time data stored in a 1st watch W1 and the time shown by the time data stored in a 2nd watch W2 . In a start mode, the time data stored in the watch W1 are rewritten into the time data shown by an absolute watch 64. At the same time, the time data stored in the watch W2 are rewritten into the time data obtained by adding the difference of times to the time shown by the time data which are rewritten into the watch W1 . Then the time data stored in the watches W1 , W2 ... are rewritten into the time data obtained by adding a prescribed time to the time decided by these stored time data every time a signal is outputted from the watch 64 after the start mode and before the stop mode respectively. |
