Assert a timestamble createdAt datetime

[ahmed-bhs]

Guys, I'm testing a product post creation, and I want to check if the timestabmle gedmo doctrine extension work correctly:

    public function testPostCollection()
    {
        $client = $this->createAuthenticatedUserClient();
        $stopwatch = new Stopwatch();
        $stopwatch->start('request');
        $client->request('POST', '/api/products', [
            'json' => [
                'name' => new product',
                'group' => '/api/groups/1',
            ],
        ]);
        $duration = $stopwatch->stop('request')->getDuration();
        $this->assertLessThan(self::WATCH_MAX_DURATION, $duration);
        $this->assertResponseStatusCodeSame(201);
        $this->assertResponseHeaderSame('content-type', 'application/ld+json; charset=utf-8');

        // Asserts that the returned JSON is a superset of this one
        $this->assertJsonContains([
            '@context' => '/api/contexts/Product',
            '@type' => 'Product',
            'name' => 'new product'
            'isArchived' => false,
            'group' => '/api/groups/1',
            'createdAt' => (new \DateTime())->format(\DATE_RFC3339),
        ]);
    }

My test fail, cause the product time creation is not a fixed in seconds.

   'isArchived' => false,
   'name' => 'new product',
   'group' => '/api/groups/1',
-  'createdAt' => '2023-10-25T20:49:08+00:00',
+  'createdAt' => '2023-10-25T20:49:07+00:00'
   'id' => 33,
 )

Does there are any right way to make my test pass ?
