Overlapping time ranges



I am trying to create a formula to show the total time a factory lin
was down during a given shift.
my problem is the overlapping times. If i just sum the times the lin
was stopped for an alarm I end
up with well over 8 hours in an 8 hour shift. the table below shows
piece of the data I get in
from the line monitor. the line was down from 05:29:58 PM until
06:01:39 PM or @ 30mins. if you
just sum the alarm times you get @ 80mins. so you can see my delema
This has got to be a tough one
or I'm just not seeing it I'm on day 2 with this problem with no avail
Please Help...

One though, the down time should be formatted as h:mm:ss,
this can be found under Format Cell Custom.

When I use this format and SUM the down time I get 1:45:13.

Hi Jeffery,

I'm quite sure you can't do this without VBA, are you ready for that?

I have been playing a bit with the sample data and may have a solution that
works. At least it does on the sample data, although it requires some
rearranging of the worksheet.

If you like, you can mail me a workbook with some more data so that I can test
the macro on a larger scale, I suppose a couple of hundred lines will do.

Nice problem btw :)
