Count occurrences and sum values with times spanning over midnight.

I am trying to count Count occurrences between two times spanning over midnight. It all works as long as the time not goes over 00:00. This is what I have

A=date and values in 2012-01-02 00:30:00 format
B=Value in 10/20/30 This is some thing I will deal with after i have figured out my occurrences problem

This is what I have come up with =PRODUKTSUMMA(--(TIMME(A2:A50)>=7);(--(TIMME(A2:A50)<=23)))
But this only works when not the time is between say start time:23:23 too 05:45 and it can not specify down two minutes criteria. Any help would be greatly appreciated
