Description:
------------

From manual page: https://php.net/datetime.diff
---


Test script:
---------------
$now = new DateTime('2018-11-03 11:34:20.781751');
$ago = new DateTime('2018-11-03 11:34:20.000000');
$diff = $now->diff($ago);
var_dump($diff);

Expected result:
----------------
On PHPv7.2.11 it gives the correct output:
Date/time in $now: 2018-11-03 11:34:20.781751
Date/time in $ago: 2018-11-03 11:34:20.000000
object(DateInterval)#574 (16) {
  ["y"]=>
  int(0)
  ["m"]=>
  int(0)
  ["d"]=>
  int(0)
  ["h"]=>
  int(0)
  ["i"]=>
  int(0)
  ["s"]=>
  int(0)
  ["f"]=>
  float(-0.781751)
  ["weekday"]=>
  int(0)
  ["weekday_behavior"]=>
  int(0)
  ["first_last_day_of"]=>
  int(0)
  ["invert"]=>
  int(0)
  ["days"]=>
  int(0)
  ["special_type"]=>
  int(0)
  ["special_amount"]=>
  int(0)
  ["have_weekday_relative"]=>
  int(0)
  ["have_special_relative"]=>
  int(0)
}

Actual result:
--------------
On PHPv7.3RC4 it give this output which is wrong:
Date/time in $now: 2018-11-03 11:50:50.826351
Date/time in $ago: 2018-11-03 11:50:50.000000
