I think I was mistaken here: it saves foo.tex as typesetting only if
document was edited (not necessarily changed. Actually TeXShop behaves
like vi: you can save file even if it has not been edited since the
previous save, thus affecting timestamp; some editors do not allow it)

Still since it is  my/Robert Bruner solution, I just think that it is
my duty to warn about problems
arising from the use of this macro.

The person who uses this macro should check that the system he/she
uses does not cause this kind of problems


\newcommand\file{foo} % put the name of your file here



 \immediate\write18{\rm -f \file.date; ls -lT \file.tex | awk '{print
$8" "$7" "$6" "$9}' > \file.date}
%need to run tex with --shell-escape; some tex guru may be will
suggest a better solution
