#25598 [Opn->Csd]: strtotime can't handle dates before 1970, and the documentation doesn't say it.

ID: 25598 Updated by: didou@php.net Reported By: bens at benjamindsmith dot com -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: 2.4.x Linux, Windows PHP Version: 4.3.2 New Comment: Fixed in CVS :) Hartmut, this was mentionned in strftime() but too specific to make an entity. Previous Comments: ------------------------------------------------------------------------ [2003-10-13 05:30:29] hholzgra@php.net UNIX timestamps for dates before Jan 1st 1970 are undefined anyway some platforms treat negative timestamps as dates before 1970 while others just consider negative values as undefined ... so this is a 'won't fix' problem unless we come up with a portable PHP C-lib ;) AFAIR this *is* documented in other places in the manual? ------------------------------------------------------------------------ [2003-09-18 17:57:42] bens at benjamindsmith dot com Description: ------------ No matter what I do, strtotime can't seem to handle dates prior to 1970. The answer returned is always -1. The manual doesn't indicate this fact. Reproduce code: --------------- echo phpversion(); echo "\n------------------\n"; $time1="1/1/1970"; $time2="31-dec-1969"; $time3="31-dec-1949"; echo strtotime($time1); echo "\n"; echo strtotime($time2); echo "\n"; echo strtotime($time3); echo "\n"; Expected result: ---------------- 4.3.2 ----------------- 28800 -{some integer other than 1} -{some bigger integer other than 1} Actual result: -------------- 4.3.2 ------------------ 28800 -1 -1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25598&edit=1
