DateTime format and control characters

[seiffert]

When using control characters like "!" in the format strings of DateTime-properties, this works just fine for deserialization, but does not for serialization. This is of course an issue with PHP's APIs and the incompatibility of format strings accepted by DateTime::format($format) and the ones accepted by DateTime::createFromFormat($format, $time). However, when using it with the serializer, this becomes an issue because there is (afaik) no way to define a separate deserialization type for a property.

Example:
Deserializing the value "2013-05-18" with type DateTime<'!Y-m-d'>, results in the following object:

DateTime Object
(
    [date] => 2013-05-18 00:00:00
    [timezone_type] => 3
    [timezone] => UTC
)

When serializing this object using the exact same type definition, this results in the string "!2013-05-18" (with the "!" as part of the result string, which is of course logical, but not intended).

Do you think, that there is a good way to circumvent this issue? If we can find one, I'd be happy to contribute by submitting a PR for it.

Encountered the same issue. Still no solution for that?
I even can't override serializeDateTime method without copying the whole class since it uses private methods for some reasons.
