I have this two variable:
$time_in = 21:00:00; $time_out = 05:00:00;
I just want to know how I should compute the number of hours of night differential:
Night differential time are:
22:00:00 - 06:00:00
I just want to know if you could suggest anything that can help me for this if their is a function for this or should I use manually compute it?
