Need formula to calculate the numbers of hours and get the value true or false

[Giri.hb]

Hi Team,

I have attached the sample file where in the A column I have approved date and time and in the B column I have ordered date and time and I need to get the values (true or false) in C column. Please check and assist.

If the orders are approved before 17:00 and the ordered date shows as same date before 17:00 then the value should come as true.
If the orders are approved before 17:00 and the ordered date shows next date or other dates it should come as false.
If the orders are approved after 17:00 and the ordered date shows next network day date before 16:00 it should give the value as true.
If the orders are approved after 17:00 and the ordered date shows next network day date after 16:00 it should give the value as false.
