sorting by date AND time

[Loru]

My problem is that u can only sorting by one of both, time OR date.
But i want to sort at first by date and than by date to.

I found out that the autor of phpRaid used this http://www.thecalico.com/software/reportlist_example.php

for the table arrangement.

But i still havn't any idea how to implement to sorty by 2 catagories. :-(

Any Ideas? :)

Thx in Advance,

Loru
