Why is this an invalid hash function?

I want to have a hash value that is based on the full date, so I created this function, where pl_datetime is a datetime type:
date_add(pl_datetime, interval 0 day)+0
this functino appears to returm an int (ie 20060511), so not sure why that isnt valid, unless it is too large.
any help would be helpful
