Title: integrate signature routine from mixpanel PHP

Thanks a ton for MixGuzzle it's been a huge help. I integrated some code from MixPanel's sample PHP routine which seemed to fix issues I was having with "invalid signature" and "expired timestamp". The code below offsets to UTC and integrates Mixpanels signature() method. Let me know if further changes are needed before integrating.
