WHY are these changes introduced?
Fixes #570 #570
During the OAuth flow we receive an HMAC that has been computer over URL parameters. One of them is a timestamp. This timestamp wasn't validated therefore allowing potential replay attack to occur.
WHAT is this pull request doing?
This PR add timestamp validation to ensure the submitted timestamp is within a reasonable windows in the past or in the future
