PHP Bug Type: Date/time related
Bug description: Setting file datetime outside of matching DST settings loses
time.
Description:
------------
Touching a file with a non DST datetime and then reading it back is
losing 1 hour.
Using Procmon, Windows is getting and returning the correct times.
It seems that PHP is adjusting the times it gets when in DST and
reading a file NOT in DST.
Reproduce code:
---------------
<?php
// Create a dummy file.
$s_File = getenv('TEMP') . DIRECTORY_SEPARATOR . 'junktime.txt';
file_put_contents($s_File, 'JUNK');
$a_Dates = array(
'Some time today' => strtotime('today 13:14:15'),
'January 1st' => strtotime('2009/02/03 04:05:06'),
'October 1st' => strtotime('2008/10/01 04:05:06'),
);
foreach($a_Dates as $s_When => $dt_Date) {
touch($s_File, $dt_Date);
clearstatcache();
$dt_Modified = filemtime($s_File);
echo
'Wanted to set the date to : (', $dt_Date, ') ', date('r', $dt_Date),
PHP_EOL,
'File was set to : (', $dt_Modified, ') ', date('r',
$dt_Modified), PHP_EOL,
($dt_Date === $dt_Modified ? 'Match' : 'Different'), PHP_EOL,
PHP_EOL;
}
// Clean-up
unlink($s_File);
Expected result:
----------------
Wanted to set the date to : (1242130455) Tue, 12 May 2009 13:14:15
+0100
File was set to : (1242130455) Tue, 12 May 2009 13:14:15
