Suggestion: why not change the site time to UTC? It is afterall pretty much an international site, right?
We have talked about doing this for the entire site - it make sense. The thing that has stopped us
has been that we are not sure what will break on the site if we move the site to UTC. We have been working on new code for the entire site and the plan all along has been that when we roll out the new code we will switch to UTC at that time.
