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?






front-end date-and-time interface

          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"|>

                    0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
