For the instantaneous period of time in between AM and PM, there is no AM or PM, just noon and midnight.

Anybody else know a better answer? 
A.M. stands for "ante meridiem"
P.M. stands for "post meridiem"
Meridiem=Noon
Ante=before
Post=after
Therefore, by definition, noon cannot be AM or PM. By the same token, midnight cannot be either because it is a point in time that divides the day up.
