note 107252 added to datetime.construct

The DateTime class should not assume that because my input is a timestamp that my desired output will be either within the same timezone as UTC or formatted in a way that contains timezone representation. It incorrectly assumes (in my opinion) the UTC timezone when it should instead use the timezone provided by the programmer to properly offset the date. The class should assume that the programmer knows what they are doing when they pass a timezone that is different from the one that is represented in the time parameter (if one exists). The expected functionality would be that this class would automatically offset a date that contains timezone representation (like a timestamp) to the provided timezone when the class is instantiated. This is PHP's default way of handling timezones with the date() function and should be consistently followed here. For example, one would expect the two following ways to output a date would be the same. However, the DateTime object completely ignores the timezone provided. My proposal for how this class should function is that when a timezone is specified through the time parameter along with an additional timezone, it should use that additional timezone to offset the date from its specified timezone within the first parameter. <?php // Using the same timestamp, timezone, and format $timestamp = 1306123200; $timezone = 'America/New_York'; $format = 'Y-m-d H:i:s'; // Old Way date_default_timezone_set($timezone); echo date($format, $timestamp); // ACTUAL output "2011-05-23 00:00:00" // New Way $date = new DateTime('@' . $timestamp, new DateTimeZone($timezone)); echo $date->format($format); // ACTUAL output "2011-05-23 04:00:00", EXPECTED output "2011-05-23 00:00:00" ?> ---- Server IP: 69.147.83.197 Probable Submitter: 108.203.169.225 ---- Manual Page -- http://www.php.net/manual/en/datetime.construct.php Edit -- https://master.php.net/note/edit/107252 Del: integrated -- https://master.php.net/note/delete/107252/integrated Del: useless -- https://master.php.net/note/delete/107252/useless Del: bad code -- https://master.php.net/note/delete/107252/bad+code Del: spam -- https://master.php.net/note/delete/107252/spam Del: non-english -- https://master.php.net/note/delete/107252/non-english Del: in docs -- https://master.php.net/note/delete/107252/in+docs Del: other reasons-- https://master.php.net/note/delete/107252 Reject -- https://master.php.net/note/reject/107252 Search -- https://master.php.net/manage/user-notes.php
