![](/common/images/spacer.gif) This notebook defines two functions to do time arithmetic. TimeAdd[tstart, dt] increments a start time by a given amount. TimeBetween[tstart, tstop] gives the difference (stop - tstart). The format of all time arguments is {year, month, day, hour, minute, second}, which is the same as that used by the built-in Date function. The time increment, dt, can be positive or negative. All arguments are integers.
