Off the top of my head, I guess that depends on the actual accuracy 
required (ie, how many clock ticks elapse between querying the time and 
the high-resolution timer).  Starting at 0 works fine for profiling in a 
single process, the predominant use-case when this was done; I guess it 
depends on the specific requirements and time-intervals being dealt with 
in the cross-process case which determines how suitable that might be?
