The year 2016 will be one second longer than most years. The U.S. Naval Observatory will add one ‘leap second’ to its atomic clock on December 31, 2016. All time zone clocks in the U.S. base their time on the atomic clock at the Naval Observatory. The reason for this is that the speed at which the Earth rotates on its axis varies slightly depending on climatic and geological conditions, and the Earth is slowing down. Every year, it takes the Earth a fraction of a second longer to go around the Sun than it did the previous year. As a result, a ‘leap second’ has to be added to the calendar every 500 to 700 days. That, in turn, means that if you rent your home, you will be getting one second of free rent this December! Now it seems to me that we landlords would be justified in raising our rents for the month of December this year since our tenants are going to get to live in their apartments for one second longer than they did last December. I haven’t heard of any landlords planning to do that, but it wouldn’t surprise me if some did. We landlords do not like to give away free rent, even its just one second every few years.
