Description:
------------
Test fails for both TS/NTS regardless of opcache on/off but only for x86. My machine is x64, if that matters. 

Failed Test Location: ext\standard\tests\file\bug49047.phpt

Test script:
---------------
<?php
// fopen with interesting windows paths.
$testdir = __DIR__ . '/bug47177.tmpdir';
mkdir($testdir);
$t = time() - 3600;
touch($testdir, $t);
clearstatcache();
$t2 = filemtime($testdir);
if ($t2 != $t) echo "failed (got $t2, expecting $t)\n";
rmdir($testdir);
echo "Ok.";
?>


Expected result:
----------------
Ok.

Actual result:
--------------
failed (got 2133437328, expecting 1562957009)
Ok.

This bug has the same cause as bug #78282, so I'm closing as
duplicate.

This test still fails for PHP-7.2.21 and PHP-7.3.8 for x86 only regardless of opcache on/off. 

There is a slight difference though. 

An output for 7.2.21:
failed (got -34, expecting 1565129706)

An output for 7.3.8:
failed (got -185, expecting 1565129706)

Running each one multiple times gave different values that were "got x". The value always increased, but not by a set amount.

This bug will be fixed in PHP 7.2.22 and 7.3.9 (and has already been fixed in 7.4.0beta1).
