I am having an issue with NOW() .
Unfortunately for you, NOW() means "now"; it may be that you need a
THEN() function!
I am using =IF(ISBLANK(A3),"", IF( ISNUMBER(B3), B3, NOW() ) )
I have copied this by dragging the corner of the cell to 100 other
cells the problem is when i enter data into a cell in column 3 ...
Er, column A, perhaps?
... the time changes in every cell in column 3 and it should not.
You clearly don't want it to, but since NOW() means "now", it
should. By default, each time you make changes to a spreadsheet,
formulae are recalculated, and since all your formulae contain a
reference to NOW(), that will be updated to the current date and
time, not the one at which previous changes were made.

This reply confuses me. The OP is using NOW() as the final option in
a nested IF() statement. So, to my understanding, NOW() should not
be executed unless both of the first two options fail. Otherwise, it
appears that the mere presence of the NOW() statement as one of the
options causes the rest of the IF() statement to be rendered null
and void. To me, that behavior makes it a bug.
But both the IF() tests *will* fail in the circumstances the
questioner is referring to: they failed when he entered data on other
rows earlier - and caused the date and time to be produced in the
cell - and will do so again when the formula is recalculated as a
result of a new entry on a different row. On any row where either of
the IF conditions is true, NOW() is indeed not used and no problem is seen.
