Subject: Re: [PHP-DEV] RFC for Adding __toString to DateTime

as i said above, a global option will make this feature completly unusable
for libraries. For Doctrine we would really like to have __toString() for
datetime primary keys (identity map), but  we need a reliable stable
lossless format that can never change.
