 A note on inter-event timestamps: If common_timestamp is used in a
 histogram, the trace buffer is automatically switched over to using
-absolute timestamps and the "global" trace clock, in order to avoid
-bogus timestamp differences with other clocks that aren't coherent
-across CPUs.  This can be overridden by specifying one of the other
-trace clocks instead, using the "clock=XXX" hist trigger attribute,
-where XXX is any of the clocks listed in the tracing/trace_clock
-pseudo-file.
