Description:
------------
Function date_format($now, "Y-m-d\TH:m:s.v") returns "1000" milliseconds after "999", but it must be a "000".

Test script:
---------------
<?php
for ($i = 0; $i < 3000; $i++) {
  $now = new DateTime();            
  $t = date_format($now, "Y-m-d\TH:m:s.v");
  echo $t . "<br>";
}
?>

Expected result:
----------------
2017-06-13T11:06:22.998
2017-06-13T11:06:22.999
2017-06-13T11:06:23.000

Actual result:
--------------
2017-06-13T11:06:22.998
2017-06-13T11:06:22.999
2017-06-13T11:06:22.1000
2017-06-13T11:06:23.000

Due to the rounding also being done this will happen for microseconds >= 0.999500. https://3v4l.org/NNDZV

This appears to be fixed as of PHP 7.2.0rc1.

Example script:

  $dateTime = new \DateTime('2017-09-29 17:44:48.999600');
  var_dump($dateTime->format('Y-m-d H:i:s.v'));

Output for 7.0.0 to 7.2.0beta3:

  string(24) "2017-09-29 17:44:48.1000"

Output for 7.2.0rc1 to 7.2.0rc2:

  string(23) "2017-09-29 17:44:48.999"
