    Time calculations subtraction and average

    ok folk I'm new here, so please bare with me. 1st problem concerns entering data as text and it being converted to time. I have found the formula 00\:00 which does an excellant job of converting. However, when I want to subtract, (=a2-a1) for example, it treats the time as a number. Sometimes it works, but if the hours are different, say 23:30- 22:10, it will subtract 2330-2210! Is there a way to make this work?
    2nd problem, related to the first is when I try to avg a column of times, I get a similar effect. I believe the answer to the 1st may help resolve the 2nd, but I'm not sure. any have any thoughts?

    First of all why would you want to enter times as text which means you can't use time arithmetic until you do convert them to time numbers?

    If it's a case of wanting to see two times in the same cell, then capture them first in two cells as proper time numbers and then concatenate them in a third cell as text. Then do your arithmetic with the first two cells.
