Yes, even you can use CPAN. You can install perl modules in your home directory, or into your build tree (along with your code). Either that, or you can't even install your code so the question is moot.

Now that you CAN use modules, you may want Text::CSV_XS to handle tab-separated data (though it may be overkill at this point, I always like planning for as much flexibility as possible, and since I don't need to write the code but merely call it, all the better). But you almost definitely DO want Date::Parse for parsing those strings into unix-times that you can use for simple comparison.
