Description
At the moment, we have three constraints for validating date/time values:
Dateaccepts\DateTimeinstances and 'Y-m-d' stringsDateTimeaccepts\DateTimeinstances and 'Y-m-d H:i:s' stringsTimeaccepts\DateTimeinstances and 'H:i:s' strings
I think that's a bit confusing. Usually, a value should not be a \DateTime or a string, but either of them; if it is a string, it should usually match a specific pattern.
Therefore I propose to deprecate all three constraints. The \DateTime case can be solved with the Type constraint already:
/**
* @Assert\Type('\DateTime')
*/
private $createdAt;The second case would be covered by a new Timestamp constraint which accepts a format as argument as supported by PHP:
/**
* @Assert\Timestamp('Y-m-d')
*/
private $createdAt;
/**
* @Assert\Timestamp('c')
*/
private $iso8601Date;
