PHP Bug Type: Date/time related
Bug description: DateTime::diff() corrupting microtime() result
Description:
------------
calling DateTime::diff() seems to corrupt the result returned by
microtime(), so it returns the wrong time after this function has been
called
Reproduce code:
---------------
<?php
// two arbitrary dates
$date1=new DateTime("2005-07-23");
$date2=new DateTime("2006-02-14");
echo "<pre>";
var_dump(microtime());
var_dump(time());
var_dump(date(DATE_ATOM));
var_dump($date1->diff($date2));
var_dump(microtime());
var_dump(time());
var_dump(date(DATE_ATOM));
echo "</pre>";
?>
Expected result:
----------------
Expecting the 2nd microtime to be slightly bigger ( by a few miliseconds )
than first.
instead, it's a totally wrong 50000 seconds distance (or maybe other
arbitrary value)
date() and time() seem to be unaffected
Actual result:
--------------
before calling diff:
string(21) "0.98425000 1241761004"
after it:
string(21) "0.25882200 1241709345"
