PHP中的strtotime（）转换错误

Question

My variable $createdDate has a value '2014-06-23T01:44:22Z' something like this in it. It's fetched from database.

And when I convert it into standard format using strtotime(), the time returned is always 2 hours different(ahead) from the orginal variable's time.

$time1 = strtotime($createdDate);
$cretime_formated=date("Y-m-d h:i:s",$time1);

Output of $cretime_formated is 2014-06-23 03:44:22 instead of 2014-06-23 01:44:22 . Why is there a difference of 2 hours in the time??? Is there anything wrong with my conversion process??

Answer 1

鉴于日期在Zulu时区中（并且假设所有此类时间戳都在同一时区中），则需要gmdate()进行格式化：

$cretime_formated = gmdate("Y-m-d h:i:s",$time1);

Answer 2

I think you have the time difference .You need to set it in UTC

date_default_timezone_set('UTC');
