Using timestamp is a poor technique for forming unique filenames.
Someday, you *WILL* get two requests in the same second. Use
File::Temp. Even better -- don't use a file at all. I generate PDF
and Excel spreadsheets all the time, and I never write them out to files.

In your headers, you want to put something like
Content-type: application/x-tex
Content-disposition: attachment; filename="custom-file.tex"

The browswer will *ALWAYS* open a dialog, but it should be `primed'
with the name you have suggested.

Computer software consists of only two components: ones and
zeros, in roughly equal proportions. All that is required is to
sort them into the correct order.
