ID: 13726 Updated by: alan_k@php.net Reported By: idisid@kyungmin.ac.kr Status: Closed Bug Type: Date/time related Operating System: windows NT4.0 PHP Version: 4.0.6 New Comment: try looking at the Date Package in PEAR pear.php.net Previous Comments: ------------------------------------------------------------------------ [2002-11-20 19:39:38] john@spamboxrecnot.com My ISP is using a new release of glibc and now mktime strtotime are not working for dates prior to 1970. I need to be able to add subtract a day from dates between now and before 1870.... anybody ? ie http://www.boxrec.com/date_search.php I need to generate the dates either side of the search date for the forward / backward links. ------------------------------------------------------------------------ [2002-11-14 06:46:59] derick@php.net In our fine manual: http://www.php.net/manual/en/function.date.php ------------------------------------------------------------------------ [2002-11-14 06:42:53] michael@liquidbytes.net What's the offical suggestion for getting UNIX timestamps for dates < 1970? Or is it not allowed to use them this way? BTW: The offical PHP docs say, that dates between 1902 and 2037 are _allowed_. But you say "so stay away from undefined value ranges"!? Very strange. Can you explain that to the users/developers community? ------------------------------------------------------------------------ [2001-10-18 05:55:54] hholzgra@php.net behaviour of unix timestamp functions for dates before 1.1.1970 is simply undefined and depends on the system *and* c library implementation you use so stay away from undefined value ranges :) ------------------------------------------------------------------------ [2001-10-18 02:31:32] idisid@kyungmin.ac.kr mktime(0,0,0,1,1,1969); is return -1. but in linux renturn valid value; maybe before 1970 bug in win32 version. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=13726&edit=1
