note 98936 added to function.timezone-name-from-abbr

It seems to me there is not 1-to-1 relation to go from $gmtOffset and $isdst to timezone. Correct me if I am wrong, but if $isdst = 0, it might mean that the timezone currently has no daylight saving or that the timezone has never daylight saving. How can this function differentiate between the two? ---- Server IP: 69.147.83.197 Probable Submitter: 93.97.193.240 ---- Manual Page -- http://www.php.net/manual/en/function.timezone-name-from-abbr.php Edit -- https://master.php.net/note/edit/98936 Del: integrated -- https://master.php.net/note/delete/98936/integrated Del: useless -- https://master.php.net/note/delete/98936/useless Del: bad code -- https://master.php.net/note/delete/98936/bad+code Del: spam -- https://master.php.net/note/delete/98936/spam Del: non-english -- https://master.php.net/note/delete/98936/non-english Del: in docs -- https://master.php.net/note/delete/98936/in+docs Del: other reasons-- https://master.php.net/note/delete/98936 Reject -- https://master.php.net/note/reject/98936 Search -- https://master.php.net/manage/user-notes.php
