Negative Time Error

Hi guys

I'm trying to calculate the delay between two duration, I used a straightforward formula A1-B1 and it's working fine till the result comes in a negative form it came as endless ########

Ex.1 (If result positive)
Target Response Time (A1) = 27:00
Actual Response Duration (B1) = 5:24
Expected Result (C1) = 21:36

Ex.2 (If result negative)
Target Response Time (A1) = 27:00
Actual Response Duration (B1) = 30:24
Expected Result (C1) = -02:36
 
Maybe this will solve your issue...
Go in the file menu, option, advanced, section "when calculating with this workbook "
and select USE "Use 1904 date system"

Will this affect any other calculation I have in the same workbook?
 
Hi,

Malbarki,

Just remove the - sign from your text function and check the 1904 date system in option. I think you will get your result.

Regards!
 
Hii malbarki,

Please try this in cell C2:

Code: 
=IF(HOUR(A2)>HOUR(B2),0,"-"&TEXT(ABS(B2-A2),"HH:MM"))

Hope that helps..
 
Hi malbarki,

Going on your first example
Ex.1 (If result positive)
Target Response Time (A1) = 27:00
Actual Response Duration (B1) = 5:24
Expected Result (C1) = 21:36

Ex.2 (If result negative)
Target Response Time (A1) = 27:00
Actual Response Duration (B1) = 30:24
Expected Result (C1) = -02:36
Click to expand...

Try this
=IF(A1>=B1,A1-B1,"-"&TEXT((B1-A1),"hh:mm")) and copy down, this will give any negative time values as TEXT all the others will be NUMERIC

BTW - I get -3:24 in Ex.2, don't know how you arrive at -2:36?

There's some issues with some of the entries..See attched file

As for Ex.2 you're right it's look like i'm starting to lose my focus with all these numbers o_O :oops:

Hi,

In your spreadsheet all your values are TEXT, so does this work for you?

=VALUE(A2-B2) copy down and format the cells to [h]:mm
