Date

Validates if input is a date:

v::date()->validate('2009-01-01'); // true

Also accepts strtotime values:

v::date()->validate('now'); // true

And DateTime instances:

v::date()->validate(new DateTime); // true

You can pass a format when validating strings:

v::date('Y-m-d')->validate('01-01-2009'); // false

Format has no effect when validating DateTime instances.

Message template for this validator includes {{format}}.
