File attributes changing

Continuing the discussion from Call for ideas: what should be the next BinaryAge product?:

I would really like to be able to ‘touch’ a file to change its last modification date - the info panel could perhaps be enhanced to include this …

Such things can be done via command line:

touch -mt 201404011200 file

Or if u want a gui, write a little apple script und add it to services:

That is how I would do it.

Anyway, having such a feature in info-panel would be very sleek.
Although in my cases I more often use the terminal for this, cause if I need to do it, I retouch more than one file at once.
