This is my Q838 field: 3/3/2010 4:06:08 PM
This is my T838 field: 3/3/2010 8:22:42 PM
This is my function:
=((NETWORKDAYS(Q838,T838)-1)*("10:00"-"01:00")+MOD(T838,1)-MOD(Q838,1))*24

What I get is 16:06
what I would expect to get is 4 hours 16 minutes and 34 seconds

What did I do wrong in the function to get such a difference?
