Need help about Apple Push Notification

Question

May I get the exact date and time when the push was received by the device (inside the "didReceiveRemoteNotification" function) after I tap on it. Actually I need to run a timer of 30 secs from the time when Push is received by the device. Please help me out of this problem.

Thanks in advance.

You can receive a callback in the background when the push notification is received. (source)

application:didReceiveRemoteNotification:fetchCompletionHandler: is called when the notification arrives and could be a good place to start your timer.

It seems that there is only 1 catch, if the user force closes your app by swiping it up in the task switcher you won't receive this callback again until they launch your app again.
