Previous Comments: ------------------------------------------------------------------------ [2002-07-03 12:48:48] emetsger@jhu.edu Changed status back to Open. ------------------------------------------------------------------------ [2002-07-03 12:45:30] emetsger@jhu.edu Please do not call this bug bogus. I submitted this bug in 2001, and since then I have upgraded to 4.2.1 as listed in my phpinfo() page. The test links have been updated to work properly, and the bug still exhibits the buggy behavior. ------------------------------------------------------------------------ [2002-07-02 16:33:50] eru@php.net Thank you for taking the time to report a problem with PHP. Unfortunately your version of PHP is too old -- the problem might already be fixed. Please download a new PHP version from http://www.php.net/downloads.php If you are able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". Again, thank you for your continued support of PHP. ------------------------------------------------------------------------ [2002-07-02 16:26:09] gg3po@hotmail.com Addionally, I've descovered that when PHP gets a timestamp from a UNIX file that was created/modified on the first day of any month ( use ls -al from the command line to verify the actual date modified), PHP returns the mday (in the case of getdate()), or "d" (in the case of date()) as being the last day of the PREVIOUS month + 1 day, instead of returning 1, which is the actual day of modification/creation. It doesn't even try to claim it's day 0. It just invents an imaginary day for the previous month and returns that. It also gets the "m" (date()), or 'mon' and 'month' (getdate()) values wrong, returning them as those of the previous month. Try using date("m - d", $timestamp_from_unix_file); if you don't believe me. BTW, the $timestamp_from_unix_file in the example above, actually has to be FROM a REAL unix file, not a PHP generated unix timestamp. Use filemtime($filename) to get it. ------------------------------------------------------------------------ [2002-01-24 00:19:16] emetsger@jhu.edu calling date("m-d-y H:m:s", $timestamp) doesn't always produce the correct system date. The linked page and source demonstrate this problem. The date is gathered from three different sources on the system: the date command, the date within mysql, and the php time() function call. The three different sources all produce identical timestamps. However, when I call the date() function with the above timestamp, the system date will not match the formatted date returned by date(). I saw this problem orginally in my 4.0.6 install, and just upgraded to 4.1.1 and my test page still exhibits the same behavior. The page is located at: http://esm.mse.jhu.edu/cms/test/testdate.php The source is at: http://esm.mse.jhu.edu/cms/test/testdate.phps My phpinfo page is at: http://esm.mse.jhu.edu/cms/test/index.php Thanks for taking a look!
