No it means in a million years, the total angle traveled by the earth will be 3 x 10^-6 seconds x 10^6 years x 365.25 days/year x 360 degrees/day x 1day/86400 = ~4.6 degrees greater or about an additional eighth of a revolution. The effect on the length of day will still be 0.000003 seconds per day.

Which is exactly what I said in a different way. (duh)

Uh, no, it's not at all. He (or she) is right & you are wrong.

I think not. You seem to imply that there's a deceleration of 3 microseconds per year for a million years? I read it that way. Sorry.
