You do not. Excel does not record the change date of an individual cell.
=It can be possible most of the time it is..=
At any one time you can only be working on one cell in Excel, like when you are typing data. Even if you have many cells selected, only one can actually be used. That cell is the active cell. All other cells are inactive. So an inactive cell is any cell that is not the active cell.
You can make a time table in Excel to show schedules of many things (trains, airplanes, etc.).
Try this formula: =NOW() If you don't want the time, the formula is =TODAY()
"=rand()" in a cell gives a random number between 0 and 1. Every time the sheet is recalculated (F9 key) a new random number is generated.
Excel does not have the ability to time-stamp entries. The only date-stamp you can get is the file date when you save the file. Of course, you could write a macro to record the time of the entry.
It copies what is in the selected cell or cells at that time.
If autocalculate is turned on (default setting), Excel will automatically recalculate all cell values in real time any time a referenced cell is changed.

At any moment in time, at least one cell has to be selected in Excel. It is known as the active cell. There has to be a focal point so that data or formulas can be typed in. Even when more than one cell is selected, there is only one active cell. Which cell is the active cell can be changed at any time, but there always has to be an active cell. If there isn't then, before you do anything, you would have to make a cell active. Cells are fundamental to Excel so there has to be an active cell at all times.
Time can be the formatting of clock times. There is also a function called Time which can display a time combined of hours, minutes and seconds.
