In high school I calculated a system of decimal time periods and equated them to hours/minutes/seconds, just for fun. I realized it would never work when 1/100 of a day came out to 14.4 minutes; the TV stations would need to remove 72 seconds of advertising from every half hour show, something they would never do.
