Re: Elapsed Time

Dear John:

Why not? If your sample is the case (and I do not know that it is), then
you would know the machine was down for 70 minutes a total of 3 times out of
28 days (all of February, if that is the case).

(28 * 24 * 60 - 70) / 3

(days * hour per day * minutes per hour - down time) / number of failures

Seems sufficient to me! What am I missing?

Ok, let's see if I understand.

On February 21 machine XYZ was down for 10 minutes.
On February 21 it was down again for 15.
On February 24 it was down for 45.

What's the time between failures?

You don't appear to have any information in your table which would
allow Access (or anything else) to answer the question, or perhaps I
don't understand the question.
