Measure the total time zone change of a multi-leg trip.
The total time zone shift is simply the number of zones crossed, while layovers add their own hours of sedentary time. Summing them frames how much your body clock and schedule are disturbed in one trip. A multi-leg trip compounds both clock shifts and long waits, so measuring the total exposure helps you plan recovery and rest.
