使用PHP在MSSQL上插入日期时间

I am trying to insert a datetime into an MSSQL database, but I do not get it, I always get an error. I have read all over the internet and there is no one who has had a problem like this, what can it be?

<?php
error_reporting(E_ALL); 
ini_set('display_errors', 1);
require "init.php";

$name = "20498090R";
$entSal = "1";
$ts = "2017-04-19 13:36:43";
$motivos = "";
$actividades = "";
$laobra = "PRY12345";

$newdate = date('Y-m-d H:i:s', strtotime($ts));

$pruebas = sqlsrv_num_rows($probar);

$comprobar = "SELECT * FROM [dbo].[Empleados] WHERE NIF ='".$name."';";
$probar = sqlsrv_query($con, $comprobar);

if(sqlsrv_has_rows($probar) === false){
echo 'Usuario no registrado en el sistema';
}else{

$sql = "INSERT INTO [dbo].[Fichajes] ( Empleado, Obra, Hora, Entrada, 
Motivo, Actividad) VALUES ('".$name."','".$laobra."','".$newdate."','".$entSal."','".$motivos."','".$actividades."');";

if(!sqlsrv_query($con, $sql)){
    die( print_r( sqlsrv_errors(), true));

}
}
 ?>

ERROR MSJ:

Array ( [0] => Array ( [0] => 22007 [SQLSTATE] => 22007 [1] => 242 [code] => 242 [2] => [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Converting the varchar data type to datetime produced a value out of range.

[message] => [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Se termin� la instrucci�n. ) )

If I do not do the $newdate variable the same problem I have
