Description:
------------
On PHP 7.2.20 64-bit, on Windows, touch() cannot set a file's date to a date after 2038. filemtime() will read such a file's date fine (date was set with an external tool).

Test script:
---------------
<pre><?php
$filename = 'C:\\Test\\TestFile.txt';
for ($i = 2037; $i <= 2040; $i++) {
  $t = mktime(1,1,1,1,1,$i);
  echo 'Date: '.date('D, d M Y H:i:s', $t).'<br>';
  touch($filename, $t);
  clearstatcache(true, $filename);
  $file = filemtime($filename);
  // This will be wrong for 2039 and 2040
  echo 'File: '.date('D, d M Y H:i:s', $file).'<br><br>';
}
?></pre>


Expected result:
----------------
