Loreno,

I don't know what you mean with "global count down timer", if you want to
trigger an action upon the end of the global count down you can use the *
cron* implementation.

Can you explain what is the use that you want with this? In "low-level
speaking", the only ways to share state across multiple instances / requests
safety from concurrent access issues and given the cloud nature of it is use
the datastore and memcache.
