We abandond the sun? You did that when you changed from Solar Time to Time zones. And again with Daylight Savings Time.. And I looked up the change in time on Wikipedia, and calculated a year gets 1 second longer every 150 years or so, so in 2200 we would have a leap second every year, in 2350 we would have a leap second twice a year, etc.
P.S. Ever compare time between an Android Phone and an iPhone? The network time is based on the Unix standard of seconds since 1970-01-01, ignoring subsequent seconds. iPhones are coded to add the leap seconds before displaying the time, Androids are not.
