To reproduce this - Enter 17:00:00 in A1 - Enter 17:30:00 in A2 - Enter this formula in B2: =A2-A1 - Enter this formula in C2: =A2-A1 - change format of B2 to UU:MM:SS - change format of B3 to [UU]:MM:SS The value shown in B2 is 00:30:00, while in C2 00:29:59 is shown. This is not an acceptable rounding error!
"This is not an acceptable rounding error!" should have been: This is not an acceptable way of formatting data!"
