问题 For my app functionality, I need to have a correct time set on a device. For example, I use AlarmManager to do some action at 7:00 AM. It's a tablet with Wi-Fi connection.

Is there any way to do this in php code, or any webservice to convert it? This is my last step in complete mastery in timezone programming! :) Edit: As one person

问题 I have no idea how to use datetime.tzinfo module. I have to convert a datetime data from UTC to local timezone and if I retrieve '+2'(which means gmt+2) how do I convert this to tzinfo object?
