title: How can I force Firebase to give me a new serverTimeOffset instead of caching it?
body: <p>I'm using Firebase to have a countdown across multiple users.  I use the Firebase .info/serverTimeOffset to calculate what the time should be across clients.  The problem is that the value gets cached, and so far the only way I've been able to get past the caching is to do a full reload of the firebase library, and then create a new Firebase object, and then use that one.  That has been the only way to get an updated offset so far.  Is there a better way?</p>
