title: Most current edit on Mobile<->Web App Two Way Syncronization
body: <p>The title basically says it. I have an application which is usable as a web app anda mobile app. The mobile app receives and sends data to the server. There are several cases to cover when doing a sync but I need to somehow know which is the most current edit. I plan to sync at start and stop of the mobile app. The most difficult case is probably when the user starts the app without internet and closes it still not having internet. How to solve this?</p>
  
  <p>Please note that timestamps are useless since you are on a mobile device where the clock might be changed by the user.</p>
  
  <p>What would you suggest? I don't want to ask the user about conflict solving but implement some automation. (Just take the most current one)</p>
  
  <p>Thanks</p>
