Assuming you are compiling with pdftex as backend (which is most probably the
case, as all more or less recent LaTeX-Distributions use it by default -- even
when compiling to dvi), you can use the \pdffilemoddate{<filename>} built-in
command to retrieve the "last modified" date of <filename>.
LyXically and applied for the own source file this comes down to the following
two lines, which should be inserted into your document's preamble:
\def\parsedate #1:20#2#3#4#5#6#7#8\empty{20#2#3/#4#5/#6#7}
\date{\expandafter\parsedate\pdffilemoddate{\jobname.tex}\empty}
(You can alter the display format, e.g., to use full stops instead of hyphens
as separators, by modifying the \empty{} part of the first line.
I have found the basics of this trick on the net some time ago, so I do not
want claim authorship for it. Note that in its current form \parsedate only
works for the years 2000 -- 2099.
