How to upload automatically files depending on time, date?

[epamnp]

Does anybody know how to upload on my site automatically files (e.g. flash) depending on the time and date?
I mean at 1-1-2008 13:00 the file_1, at 1-1-2008 14:00 the file_2, at 1-1-2008 18:00 the file_3, etc.
I use PHP, MySQL, Apache.

you can do that using a cron job on your cpanel and a normal uploading script
