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"|>

                    A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

                    Image
                    0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
