The value obtained by subtraction is the number of seconds of difference, and when this number of seconds is taken as the remainder of 86400 (seconds of a day), the difference is obtained. If the mode is taken for 86400 and the remainder is taken for 3600 seconds and 60 seconds, the relevant hours and minutes are obtained. If the mode is taken for 86400 and then for 60, the number of seconds of difference will be obtained.
