Would it be ok for the datetime validator to be extended with the following features (similar to Respect\Validation) ?

• Provide a custom format https://github.com/Respect/Validation/blob/master/docs/Date.md
• Provide min and max https://github.com/Respect/Validation/blob/master/docs/Min.md
• Provide an interval (between) https://github.com/Respect/Validation/blob/master/docs/Between.md

Possibly some of this can already be done with the LessThan and Range constraint ??
