OAuthGoogleExample not executing

[GoogleCodeExporter]

BEFORE YOU POST A NEW ISSUE, PLEASE CHECK THAT...

1) ... you are absolutely 100% sure that it's a bug in Signpost, and not a
problem related to the service provider you're using, or with your own code

2) ... if you're even slightly unsure about 1), post your problem to the
mailing list first, it's much more likely that you get help there:
http://groups.google.com/group/signpost-users

3) If 1) and 2) check out, always post an executable piece of code that
let's me reproduce the issue, otherwise I feel inclined to immediately
reject it

If you're still sure you found a bug, please follow the steps below.
REMOVE THIS MESSAGE BEFORE PROCEEDING.

solved it, this is at least third time, I got into the same issue... I am using 
Virtual machine using VBox for development, on EOD I hibernate my PC and VM 
clock get out of sync, and according to OAuth, server and client should not be 
offset by more than 5 minute. That's why I was having that exception.

But it could be an issue on signpost side, that it don't notify that error 
occurred due to time difference.
