Ivan,
> Is there any way we can get the Timezone selected by the user in the operating system from running Flex application? The short answer is no. > 720 minutes after UTC can mean "Auckland, Wellington" or "Fiji" The above is only true when "Auckland, Wellington" is not on Daylight Saving Time (DST,) -- since "Fiji" does not observe DST, and that, I suspect, is the real issue. You can use getTimezoneOffset() to calculate many of the DST details of the client machine. For example: */ // Test for local DST public function hasLocalDST():Boolean{ var y:Number = new Date().getFullYear(); var s:Number = new Date(y, 0).getTimezoneOffset(); var e:Number = new Date(y, 5).getTimezoneOffset(); if(s != e){ // DST is observed return true; }else{ // DST is not observed return false; } } Similarly, for locales that observe DST, you can work out exactly when DST starts and ends, whether the locale is in the Northern or Southern hemisphere, and whether the locale is currently on DST. All assuming, of course, that the client machine's time settings are correct for the locale.
