It works very well, however, every once in a while a leap second is needed.Now I'm curious, does adding one more day every 4 years work out perfectly or, will they at some point add 2 days or, skip adding the extra day one time?
Leap seconds are added to account for variances in the Earth's rotation not problems with the leap year rule.It works very well, however, every once in a while a leap second is needed.
