Afaik \DateTime object already implement a way to be used with <,>,etc.
but they don't use an interface for that.

$ php -r '$past = new DateTime("-1 month"); $future = new DateTime("+1
month"); var_dump($past < $future);'
bool(true)

$ php -r '$past = new DateTime("-1 month"); $future = new DateTime("+1
month"); var_dump($past > $future);'
bool(false)

Shouldn't they retroactively be adopted to that? Extend from that
Interface, implement a compoareTo?
