All exhibit the same symptom. Previous Comments: ------------------------------------------------------------------------ [2013-03-18 20:56:10] aharvey@php.net Which time zone is PHP configured to operate in (ie what do you get if you echo date_default_timezone_get())? ------------------------------------------------------------------------ [2013-03-18 20:47:40] xojins at gmail dot com Description: ------------ When using the DATE function and returning the day of the week (lowercase L format) returns the wrong day of the week for 3/10/2013. The example provided shows subtracting 86400 seconds from strtotime('03/11/2013') to return 1362888000 seconds. When passed to DATE, it returns Saturday. This is wrong and should be Sunday. You need to add 3600 to any value to calculate 3/10/13 correctly. Test script: --------------- $d1 = date('l', strtotime('03/12/2013')-(60*60*24)); //date('l', 1363060800 - 86400) = date('l', 1362974400) = Monday $d2 =date('l', strtotime('03/11/2013')-(60*60*24)); //date('l', 1362974400 - 86400) = date('l', 1362888000) = Saturday != date('m-d-y', 1362888000) $d3 =date('l', strtotime('03/10/2013')-(60*60*24)); //date('l', 1362891600 - 86400) = date('l', 1362805200) = Saturday echo $d1 . '<br>'; echo $d2 . '<br>'; echo $d3 . '<br>'; Expected result: ---------------- Monday Sunday Saturday Actual result: -------------- Monday Saturday Saturday ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64448&edit=1
