note 97025 added to function.strtotime

Always use the format strtotime("+1 day") when adding/subtracting units of time rather than manually adding 24*60*60 seconds to a timestamp, for example, as this format works as desired with Daylight Saving Time changes. If your timezone adheres to Daylight Saving Time, a situation like the following may apply to you: <?php date_default_timezone_set('America/Chicago'); // Don't do this: $today = '2009-11-01'; $tomorrow = strtotime($today) + 24*3600; print date('Y-m-d', $tomorrow); // Output: 2009-11-01 // Do this instead: $today = '2009-11-01'; $tomorrow = strtotime('+1 day', strtotime($today)); print date('Y-m-d', $tomorrow); // Output: 2009-11-02 ---- Server IP: 64.71.164.2 Probable Submitter: 24.107.148.0 ---- Manual Page -- http://www.php.net/manual/en/function.strtotime.php Edit -- https://master.php.net/note/edit/97025 Del: integrated -- https://master.php.net/note/delete/97025/integrated Del: useless -- https://master.php.net/note/delete/97025/useless Del: bad code -- https://master.php.net/note/delete/97025/bad+code Del: spam -- https://master.php.net/note/delete/97025/spam Del: non-english -- https://master.php.net/note/delete/97025/non-english Del: in docs -- https://master.php.net/note/delete/97025/in+docs Del: other reasons-- https://master.php.net/note/delete/97025 Reject -- https://master.php.net/note/reject/97025 Search -- https://master.php.net/manage/user-notes.php
