Validates that a value is a valid time, meaning either a DateTime object
or a string (or an object that can be cast into a string) that follows
a valid “HH:MM:SS” format.

Suppose you have an Event class, with a startAt field that is the time
of the day when the event starts:
# src/Acme/EventBundle/Resources/config/validation.yml
AcmeEventBundleEntityEvent:
properties:
startsAt:
- Time: ~
// src/Acme/EventBundle/Entity/Event.php
namespace AcmeEventBundleEntity;
use SymfonyComponentValidatorConstraints as Assert;
class Event
{
/**
* @AssertTime()
*/
protected $startsAt;
}
<!-- src/Acme/EventBundle/Resources/config/validation.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping"

xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping http://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd">
<class name="AcmeEventBundleEntityEvent">
<property name="startsAt">
<constraint name="Time" />
</property>
</class>
</constraint-mapping>
// src/Acme/EventBundle/Entity/Event.php
namespace AcmeEventBundleEntity;
use SymfonyComponentValidatorMappingClassMetadata;
use SymfonyComponentValidatorConstraints as Assert;
class Event
{
public static function loadValidatorMetadata(ClassMetadata $metadata)
{
$metadata->addPropertyConstraint('startsAt', new AssertTime());
}
}
type: string default: This value is not a valid time.
This message is shown if the underlying data is not a valid time.
type: mixed default: null
2.6 新版功能: The payload option was introduced in Symfony 2.6.
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to.
For example, you may want to used several error levels to present failed constraint differently in the front-end depending on the severity of the error.
