Interesting that the leap day at end of Feb every 4 years is not an issue but the leap second is? Seems arbitrary that one time unit proves problematic but another doesn't.
Don’t let the “leap” name confuse you: the two are quite different things. The extra day during leap years is included according to a predictable rule, but leap seconds are added (or potentially subtracted, but this has never happened) depending on how the rotation of the Earth slows down or speeds up, which follows no fixed rule.
