It seems to me that if one wanted to use dates as part of identifiers, you
would probably want to learn from tag URI's as defined in RFC
4151<http://www.ietf.org/rfc/rfc4151.txt>.
Tag URI's handle the problem of creating identifiers that are unique across
time -- which appears to be the use-case you're looking to address.

Thus, rather than the syntax you suggested, you'd be using something like
this: (i.e. use a comma, not a question-mark.)

acct:[e-mail],2001-09-15

The relevant ABNF bits from RFC4151 are:

> taggingEntity = authorityName "," date
> authorityName = DNSname / emailAddress
> date = year ["-" month ["-" day]]
