Bug #13900 Updated: date(I) does not correctly identify daylight saving time

ID: 13900 User updated by: bmplummer1@home.com Reported By: bmplummer1@home.com Status: Open Bug Type: Date/time related Operating System: Windows NT/XP PHP Version: 4.0.6 New Comment: I have two comments about the last entry. First... Jeroen, if you ran the same script that you put in your notes then it should have returned a 1 (one) because the date is May 1 2001 which occurs during daylight saving time. Second... On my Win XP pro version 2002, PHP 4.06 CGI version here is what I get: SCRIPT: <?php var_dump(date("I", mktime(0,0,0,5,1,2001))); ?> OUTPUT: string(1) "0" I haven't made any special changes to my PHP.ini. Do I need to load a special module to get this to work? I have been able to reproduce this on two different systems. On XP and NT 4.0 I used the PHP installer to automatically install PHP. I also reinstalled PHP 4.06 manually on the XP system but I only used the php.ini-dist config file. In the mean time... Anybody know of a daylight saving time detection script before I start writing this by hand?

Same for debian-linux. Both are correctly configured. What's your output with this script: <?php var_dump(date("I", mktime(0,0,0,5,1,2001))); ?> On my system, it returns string(1) "1" --Jeroen ------------------------------------------------------------------------ [2001-11-03 01:09:15] bmplummer1@home.com I downloaded 4.06 again and installed it manually. I have a feeling that my php.ini is somehow different than the standard because when I tried to use the optimized php.ini file I couldn't even load my script. But when I used the dist version the script worked (except for the date(I) part). I must have my PHP configured incorrectly. But why would it do it on two different computers and two different versions of PHP??? ------------------------------------------------------------------------ [2001-11-02 21:56:52] bmplummer1@home.com Tried it from the command line and got all zeros. ------------------------------------------------------------------------ [2001-11-01 15:44:10] cnewbill@php.net You said you were running it as a CGI therefore my test should be equivalent without me having to use Apache. I don't see how the CGI being called through Apache could do this. BUT jic, please try executing your PHP CGI from the command line against those test scripts and see if you get the same results. -Chris ------------------------------------------------------------------------ [2001-11-01 15:32:35] bmplummer1@home.com Well, I am getting zeros... I get in on PHP 4.06 on Windows XP pro and I get zeros on PHP 4.05 on Windows NT 4.0. both are running on Apache. Maybe that is the issue. Are you running PHP on Apache? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
