[Typo3] reset last update date of all pages

[Rob De Vries]

Hey list

I have this project that's *finaly* ready to go online. And when I say 
*finaly* I mean *F I N A L Y*
I'm telling you guys (and girls) this because it's ok for you to know, 
but I would like that other visitors don't know this.
so plz, ssst.. don't tell anyone else.

Anyway, I  would like to know if there is a good solution for reseting 
all last-update dates of all pages?

tnx
Rob
