Get string timezone from numeric timezone value PHP

2 comments

1. I would use DateTimeZone::listIdentifiers()

   $time_zones =  DateTimeZone::listIdentifiers();
   
   foreach ($time_zones as $time_zone) {
       $date = new DateTime('now', new DateTimeZone($time_zone));
       $offset_in_hours = $date->getOffset() / 60 / 60;
       echo "{$time_zone}: ($offset_in_hours)";
   }
   

   This will output something like:

   Asia/Choibalsan: (9)
   Asia/Colombo: (5.5)
   Asia/Damascus: (3)
   Asia/Dhaka: (6)
   Asia/Dili: (9)
   Asia/Dubai: (4)
   

   Then you can wrap this code inside a plugin/shortcode and use the output to reverse search your time zone.

2. No, because a time zone offset and a time zone are two very different things.

   See “time zone != offset” in the timezone tag wiki.
