Valid timeout values.

[sorter]

Hello,

In recent stable versions of django-push-notifications I see this error in logs:

Set PUSH_NOTIFICATIONS_SETTINGS["GCM_ERROR_TIMEOUT"] to send messages through GCM.

However, there appears to be no documentation on what value is expected? Seconds? Milliseconds? Some combing through the source seems to imply that this value is passed to urllib.urlopen(...) and that function appears to expect an integer for the number of seconds.

Could we add a simple label to the documentation indicating what type of value is expected?

+1 What would be an ideal value for the timeout ?
