php unix到目前为止无法正常工作

Question

i have a unix time 1410938094654 I want to convert this to date time format

 $dt = new DateTime('@1410938094654');
 $dt->setTimeZone(new DateTimeZone('Asia/Tehran'));
 echo $dt->format('F j, Y, g:i a');

But the wrong time will returned

06-11-2000 00:30:54

correct time is GMT: Wednesday, September 17, 2014 7:14:54.654 AM

also my php.ini

  date.timezone = "Asia/Tehran"

gmdate also returns the same date (wrong date)

Answer 1

DateTime accepts unixtime in seconds, and you have it in milliseconds, so you must divide timestamp to 1000 before creating new DateTime object.
