Question
Hi Tom,

I have a list of times in the following format: 06/24/2014  1:31:21 PM.  How do I subtract 4 hours from the time so that the output reads: 06/24/2014  9:31:21 AM.

Thanks.

Michael

Answer
Michael,

do you mean so that the output appears in another cell?

if so then assume the cell with the first date/time is A1 and in B1 you would put the formula

=A1-TIME(4,0,0)

that worked for me.   (make sure the cell with the formula is formatted the same as the original cell.


If you want to change the cell in place - in other words, change A1 to display 06/24/2014  9:31:21 AM

in a blank cell put in the formula
=Time(4,0,0)
Copy that cell,

Select A1 (still assuming the original value is in A1) and do a Paste Special and choose Values and subtract.

Again, that also worked for me.
