[API v2] Date time does not validate properly if the timezone is used

[DaazKu]

Calling http://vanilla.dev/api/v2/comments?discussionid=30 yields:

[
    {
        "commentID": 7,
        "discussionID": 30,
        "body": "<p>comment 1</p>\n",
        "format": "Markdown",
        "dateInserted": "2017-07-27T19:26:24+00:00",
        "insertUserID": 2,
        "url": "http://vanilla.dev/discussion/comment/7#Comment_7"
    },
    {
        "commentID": 8,
        "discussionID": 30,
        "body": "<p>comment 2</p>\n",
        "format": "Markdown",
        "dateInserted": "2017-07-27T19:26:28+00:00",
        "insertUserID": 2,
        "url": "http://vanilla.dev/discussion/comment/8#Comment_8"
    },
    {
        "commentID": 9,
        "discussionID": 30,
        "body": "<p>comment 3</p>\n",
        "format": "Markdown",
        "dateInserted": "2017-07-27T19:26:33+00:00",
        "insertUserID": 2,
        "url": "http://vanilla.dev/discussion/comment/9#Comment_9"
    },
    {
        "commentID": 12,
        "discussionID": 30,
        "body": "<p>asd</p>\n",
        "format": "Markdown",
        "dateInserted": "2017-08-14T14:42:58+00:00",
        "insertUserID": 2,
        "url": "http://vanilla.dev/discussion/comment/12#Comment_12"
    }
]

You get an error using the dateInserted field as the after parameter like so http://vanilla.dev/api/v2/comments?discussionid=30&after=2017-07-27T19:26:24+00:00

{
    "message": "after is not a valid datetime.",
    "status": 422,
    "errors": [
        {
            "field": "after",
            "code": "invalid",
            "message": "after is not a valid datetime."
        }
    ]
}

This is counter intuitive because the return type of dateInserted is DateTime... It should work properly
