4,500,000,000 divided by 70,000,000 equals 62.
If the Earth slowed 30 minutes 62 times, uh, the days would be less than zero.
Any reason why the slowing of the day would be more dramatic these last 70 million years?

Still, extrapolating back to Earth’s early years would yield a rather short day. Sources from Wikipedia [1] [2] estimate a 5 hour day after the Theia Impact that created the Moon.
