I am currently using the following formula to figure out how long a
request takes to be completed. This formula accounts for time spent
in a pending status, which is factored-out of the total.

=IF(ISBLANK(D2),B2-C2,D2-C2)

B2 = Date and Time issue was resolved
C2 = Date and Time issue was opened
D2 = Date and Time issue was placed in pending status

I need a formula that will factor-out the time after business hours; a
NETWORKDAYS formula or something similar that will work with the above
formula. Thanks in advance for the assistance.
