Do you know where I was wrong and he/she was right? I misread the article as 3 microseconds per year instead of per day.

That, and the fact that the rotation is supposed to have sped up, not slowed down. And it wasn't clear whether you mean a day a million years from now will actually be 3 seconds shorter, or if that's just the cumulative difference over that period.

Yes and I posted a correction like a microsecond after I realized I mispoke. I should get extra credit for that.

And it wasn't clear whether you mean a day a million years from now will actually be 3 seconds shorter, or if that's just the cumulative difference over that period.

Who in their right mind thinks that a 3 microsecond time difference caused by an earth quake 3 days ago would ONLY register a time difference a million years from now?

Of course it would be cumulative.
