[Dr15Jones]

Created a new base class for the Timing Service so other modules can report additional CPU time spent by a job external to cmsRun.

Thanks,
Are there some instructions for the bits we need to add to ExternalLHEProducer to make use of this?

[Dr15Jones]

This works like any other service:

#include "FWCore/Utilities/interface/TimingServiceBase.h"
#include "FWCore/ServiceRegistry/interface/Service.h"
...
edm::Service<TimingServiceBase> timing;
timing->addToCPUTime(1.0);
