#28399 [Bgs]: Getting unixtime since 12/31/1969 21:00:00

ID: 28399 Updated by: mgf@php.net Reported By: vinicius at teracom dot com dot br Status: Bogus Bug Type: Date/time related Operating System: Red Hat 8.0 PHP Version: 4.3.4 New Comment: This is expected behaviour -- the Unix epoch is 1-Jan-1970 00:00 *GMT*, so a timestamp of 0 of course equates to 31-Dec-1969 21:00 in a GMT-0300 timezone. This is clearly documented in the same note that you quote from: "valid range of a timestamp is typically from Fri, 13 Dec 1901 20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT" (See also date()/gmdate(), mktime()/gmmktime().)

Php makes unixtime from 12/31/1969 21:00:00. Isn't it a bug? Unixtime isn't from 01/01/1970 00:00:00 as you say in manual from function strtotime: '...This means that e.g. dates prior to Jan 1, 1970 will not work on Windows, some Linux distributions, and a few other operating systems....' If it's because the time, isn't it needed another argument to define it? For example: If i make a script using unixtime using -0300 timezone and, for some reason, i move it to another system that uses timezone as GMT, some results will be different. Reproduce code: --------------- <? $unixtime = 0; echo date("d/m/Y H:i:s", $unixtime) . "\r\n"; ?> Expected result: ---------------- 01/01/1970 00:00:00 Actual result: -------------- 31/12/1969 21:00:00 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28399&edit=1
