php_nub_qq Posted October 27, 2013 Share Posted October 27, 2013 Basically my website is worldwide and I need to be able to detect users' time zones and display accurate times. I have this really neat script which used to work flawlessly well until now. It needs a timezone offset which I fetch with javascript and pass through a cookie. if(!empty($_COOKIE['tz']) && $_COOKIE['tz']>=-12 && $_COOKIE['tz']<=13){ $offset = $_COOKIE['tz']; $tz = timezone_name_from_abbr(null, $offset * 3600, true); if($tz === false) $tz = timezone_name_from_abbr(null, $offset * 3600, false); date_default_timezone_set($tz); }else{ date_default_timezone_set('UTC'); } The problem is that currently the timezone I'm testing in is Europe/Helsinki, which is UTC+2 (without daylight savings), but for some reason timezone_name_from_abbr() decides 2*3600 is Europe/Paris. I'm really bad with dates and time zones, I desperately need help, please! Quote Link to comment Share on other sites More sharing options...
Barand Posted October 28, 2013 Share Posted October 28, 2013 With daylight savings param = true, offset and timezones are 1 : Europe/London 2 : Europe/Paris 3 : Europe/Helsinki 4 : Europe/Moscow With the dst parameter = false 1 : Europe/Paris 2 : Europe/Helsinki 3 : Europe/Moscow 4 : Asia/Dubai Quote Link to comment Share on other sites More sharing options...
