Dear jtakw,

Thanks for your kind help.

I have checked the cell format. It is show like that mm/dd/yyyy hh:mm:ss AM/PM

Your formula work when name changed different in Column A, When Name coming same text then its not subtract from Column B.

Name - Column A <tbody> </tbody>	Date - Column B <tbody> </tbody>
abc <tbody> </tbody>	01/17/2018 12:09:00 AM <tbody> </tbody>
Xyz <tbody> </tbody>	01/17/2018 12:09:00 AM <tbody> </tbody>
abc <tbody> </tbody>	01/17/2018 12:09:00 AM <tbody> </tbody>
abc <tbody> </tbody>	#VALUE! <tbody> </tbody>
abc <tbody> </tbody>	#VALUE! <tbody> </tbody>
abc <tbody> </tbody>	#VALUE! <tbody> </tbody>
Xyz <tbody> </tbody>	01/17/2018 12:09:00 AM <tbody> </tbody>
ASAF <tbody> </tbody>	01/17/2018 12:09:00 AM <tbody> </tbody>
Xyz <tbody> </tbody>	01/17/2018 12:09:00 AM <tbody> </tbody>

Works for me:

Excel 2010
	A	B	C	D
1	Name - Column A	Date - Column B
2	abc	01/17/2018 12:09:00 AM		TRUE
3	Xyz	01/17/2018 12:09:00 AM
4	abc	01/17/2018 12:09:00 AM
5	abc	01/17/2018 12:08:00 AM
6	abc	01/17/2018 12:07:00 AM
7	abc	01/17/2018 12:06:00 AM
8	Xyz	01/17/2018 12:09:00 AM
9	ASAF	01/17/2018 12:09:00 AM
10	Xyz	01/17/2018 12:09:00 AM
Sheet8

Cell Formulas
Range	Formula
D2	=ISNUMBER(B2)
B3	=IF(A3=A2,B2-"0:01",B$2)

Besides checking that Column B formatting is mm/dd/yyyy hh:mm:ss AM/PM, you need to input your date/time correctly, in an unused cell (in my sample D2) put =ISNUMBER(B2), if it doesn't return TRUE, you have entered B2 as TEXT, and the formula will NOT calculate.
