I went to my local planetarium recently and learnt that the earth to moon distance increases by 38mm each year, while the earth rotation slows down very slightly. Obviously not a significant amount to mean anything right now, but what will happen in the future when it will make a difference? How will people just “add time” to hours/days/weeks/months and so forth?

The rate at which earth’s rotation is slowing down is absolutely miniscule. Since the 8th century, it’s only been slowing 2.3 milliseconds *per century*. 43,000 years from now, a day will be just 1 second longer than it is today. And since today, our days are actually 3 minutes and 56 seconds shorter than 24 hours, it’s going to be over 10 million years before we’re even *at* 24 hours a day, let alone significantly *past* 24 hours a day. Humans are going to be *long* dead 10 million years from now.
