Yes, that statement annoyed me as well.. 

If you compare the cesium oscillator on the moon with the one on earth, you'll find that the one on the moon is oscillating about 0.0006794 times faster. The only way to keep the two in sync is by appying leap microseconds or leap seconds on a regular basis. 

On the moon you can't make an Earth second by dividing your oscillator by 9192631770, you need divide by 91926318480 to get a TAI-compatible second, if my early morning math is correct. 

If you do divide by 9192631770, you need 58.7µs per day in corrections to keep in sync with Earth time. 19.8ms per year.
