I have data that shows stop and end points for certain procedures. For
example, something starts at 8:00 am and ends at 12:00 pm, which is a total
of 4 hours. What I need to know is how much of this time occurs in a
particular time band, say 7 am to 10 am, which would be three hours. I need
to figure out a way to write an IF statement that will capture this. The
problem I have so far is that the IF statement I've written works for many of
the time bands, but it's not picking up time usage for some reason in the 7
am - 1 pm range, when time is definitely being used. Is there some other way
I can write the IF statement or some way I should revise it so that it'll
pick up every calculation of time usage in a particular time band?
