Might this suggest that the rotation of the Earth has been slowly accelerating?
Will we be expected to work 8 hour work days when days are only 8 hours long?

Slowing down? Awesome!
Doesn't that contradict theories of evolution a little?
The earth's rotation is definitely slowing down not speeding up, mostly because of the drag of the moon. Somehow this is also making the month longer, because the extra kinetic energy pushes the moon back a bit from the earth. I'm not sure I understand that, but there it is.
The theory continues that a day and month at some point will be the same length: about 47 days in current reckoning. Of course, we will have the 25 hour day long before that. That will be great! It will match our internal clocks (I guess) and give Maki an extra hour of sleep. It's something to look forward to in a short million years or so.
