> I am trying to figure out the purpose of EnvironmentEdge in the HBase code.
> The java doc says it has something to do with environment, I feel it is vague. It looks
like there is a bigger picture for such a design. Currently only concrete method that is available
in it is currentTime(). 
> Can anyone summarize the rationale behind having EnvironmentEdge/EnvironmentEdgeManager
