The title section of my LaTeX documents usually look like
\\title{Title}
\\author{Me}
%\\date{} %// Today\'s date will appear when this is commented out.
\
My answer is probably too late for the original thread, but Latex has a very interesting package called vrsion
(there is no 'e'), which is part of the standard distribution. Essentially, it numbers the .dvi file, i.e the number is increased every time Latex is run.
Personally, I use this as a simple work around for the lack of a human-friendly document version number from Git. Not ideal, but sometimes I have multiple copies of my documents and it helps avoid some confusion.
