5














Once a command is entered and numbered, as in In[n], and an output is produced, as in Out[n], is it possible to find the time at which each one was done?

          You can use Cell | Show Expressionfrom the menu to see the time stamps associated with a cell. If you want to do this programmatically, you could use Cells and CurrentValue:



          timeStamps[line_] := With[
          {
          cells = Pick[
          Cells,
          CurrentValue[Cells, CellLabel],
          _String?(StringMatchQ[__~~"["~~ToString[line]~~"]"~~___~~"="])
          ]
          },

          AssociationThread[
          CurrentValue[cells, CellLabel],
          DateString /@ Max /@ CurrentValue[cells, CellChangeTimes]
          ]
          ]


          An example. Set the line number:



          $Line = 1;


          Then evaluate something:



          2 + 2



          4




          Get time stamps:



          timeStamps[2]



          <|"In[2]:=" -> "Tue 4 Dec 2018 19:49:43",
          "Out[2]=" -> "Tue 4 Dec 2018 19:49:43"|>
