I have a document that it has 35 thousand entries of different times. I need
to figure out the time intervals between every single entry. The formula i
use is pretty simple =(H#-H#). For example how would i adjust that formula so
it takes in account all the 30 something thousand of other rows.

My thing looks something like this
Time Interval
12:01:03.396 AM
12:01:06.309 AM
12:02:25.823 AM
12:02:30.195 AM
12:03:49.709 AM


Is there a formula that i can get the difference between each time and add
it up for a total amount of hours....

please any advice is VERY appreciate it

Thank You
