-------------------------------------------------------------------

This patch uses {{System.nanoTime()}} in several places instead of using 
{{cloudManager.getTimeSource().getTimeNs()}}, and this will break the simulator.

Similarly, {{CoresVariable}} uses {{System.currentTimeMllis()}} (which is a 
forbidden API, too) where it should use 
{{ctx.session.cloudManager.getTimeSource().getEpochTimeNs()}} instead as the 
base for calculations.

> When rules have computed values such as "#EQUAL" or "#ALL" , it takes too 
> long to compute. The problem is these values are computed too many times and 
> as the no:of nodes increase it almost takes forever. These values don't 
> change and they can be cached
