#38781 [Opn->WFx]: strtotime() generates wrong date for 11th month 2007 on.

ID: 38781 Updated by: tony2001@php.net Reported By: rpk at npstrategy dot com -Status: Open +Status: Wont fix Bug Type: Date/time related Operating System: Linux Fedora Core 4 PHP Version: 4.4.4 New Comment: I still can not reproduce it. month11_2006_date for Friday 2006 = 17(correct) month11_2007_date = 16 (wrong) Anyway, we're not going to do any major changes in PHP4. The datetime related code was rewritten in 5.1, which you should use instead.

I get 17 and 16, both are correct results. Also, please try to be more clear when you provide reproduce code. Lot of HTML and text do not add any understanding. ------------------------------------------------------------------------ [2006-09-11 18:16:17] rpk at npstrategy dot com Description: ------------ strtotime starts generating wrong timestamps in November, 2007. Only wrong in the month of November. Rest of months are ok. strtotime("3 Friday", $november_2006_timestamp) generates correct timestamp with date which is the 3rd Friday in November 2006. strtotime("3 Friday", $november_2007_timestamp) generates wrong timestamp with date which should be the 3rd Friday in November 2007. The date generated is -1 day, in this case, Thursday in the month of November, 2007. All dates generated are wrong in the months of November. Tested up to 2009. Every other month works ok. Reproduce code: --------------- <?php $month11_2006_timestamp = mktime(0,0,0,11,1,2006); $month11_2006_day_timestamp = strtotime("3 Friday",$month11_2006_timestamp); $month11_2006_date = date('j',$month11_2006_day_timestamp); echo"<h1>month11_2006_date for Friday 2006 = $month11_2006_date (correct)</h1>"; echo"<h1>This correctly shows the 3rd Friday date for November, 2006 </h1>"; //test of strtotime() generating date string for day in 3 week in November 2007 $month11_2007_timestamp = mktime(0,0,0,11,1,2007); $month11_2007_day_timestamp = strtotime("3 Friday",$month11_2007_timestamp); $month11_2007_date = date('j',$month11_2007_day_timestamp); echo"<h1>month11_2007_date = $month11_2007_date (wrong)</h1>"; echo"<h1>This incorrectly shows the 3rd Friday date for November, 2007 <br>as the 15th of November 2007 which is a Thursday. <p>Every day-date generated from November 2007-2009 produces at -1 day from the standard. So other days are also wrong. It is always November. The other months work fine.</p></h1>"; Expected result: ---------------- month11_2006_date for Friday 2006 = 17 (correct) This correctly shows the 3rd Friday date for November, 2006 month11_2007_date = 15 (wrong) This incorrectly shows the 3rd Friday date for November, 2007 as the 15th of November 2007 which is a Thursday. Every day-date generated from November 2007-2009 produces at -1 day from the standard. So other days are also wrong. It is always November. The other months work fine. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38781&edit=1
