I'm thinking C... use time_t, and add and substract that. strftime is your
friend here. From the shell, use date with some funky formating (something
like "date +%Y%m%d%H%M.%S"). You man add and substract that, and convert
it to another format.

And yes, for what I asked, it would be a null file, and use creation date
for reference.
