i want a formula to count the amount of days and hours between 2 times.
i'm working in office 2010.
and i'm using the 24hour timerate.

i have for example 2 dates where i would like to know the amount of time it took between the 2 but without the weekends
so for example:
a1:7/2/2013 08:46
b1: 11/02/13 12:00
c1: the time inbetween without the weekends.

i've already seen some formulas like the networkdays and then you have to use the int function.
but haven't seen any example as my ow (or i didn't manage to convert to my own)

thx for the help in advance
