Hi Curt!
As Peo says, this is a no can do for any formula or function.
The best you can do by formula is to modify the return of your formula
using something like:
=IF(TODAY()>--"2004-04-01","",Yourformula)
VBA may be an option but it might be best to look at why you want to
do it first.

It is imperative that the patches provided by Microsoft in its April
Security Release be applied to Systems as soon as possible. It is
believed that the likelihood of a worm being released SOON that
exploits one of the vulnerabilities addressed by these patches is VERY
HIGH.
