time generator
Hi experts,

I'd like to generate the table/file containing:
number of milliseconds elapsed since midnight till midnight.
It should contain 5 columns (hours minutes seconds milliseconds):
Table will have theoretically 86 400 000 rows.

My question is , is there somewhere the file or source where this things are already ready to download, or what would be the fastest/easiest way to generate such a huge file?

Thanks for all comments.
