note 117999 added to datetime.sub

Keep in mind that this method can work incorrectly when the daylight saving time is changing to wintertime. An example is when you have got a loop and your subtracting 1 hour from your time in it. On one day you are actually subtracting 1 hour and the computer adds 1 - the infinitive loop is created. And on the other day you would actually subtract 2 hours. ---- Server IP: 72.52.91.14 Probable Submitter: 2001:a61:32a3:3001:c985:d57:6f8e:9ee3 ---- Manual Page -- http://php.net/manual/en/datetime.sub.php Edit -- https://master.php.net/note/edit/117999 Del: integrated -- https://master.php.net/note/delete/117999/integrated Del: useless -- https://master.php.net/note/delete/117999/useless Del: bad code -- https://master.php.net/note/delete/117999/bad+code Del: spam -- https://master.php.net/note/delete/117999/spam Del: non-english -- https://master.php.net/note/delete/117999/non-english Del: in docs -- https://master.php.net/note/delete/117999/in+docs Del: other reasons-- https://master.php.net/note/delete/117999 Reject -- https://master.php.net/note/reject/117999 Search -- https://master.php.net/manage/user-notes.php
