Yes, it was a bug that you couldn't read it as non-root. And it shouldn't be
reading the local trace_clock anyway, even if you are root.

1) because it could be splitting a trace.dat file from another machine
   (which is what I was doing)

2) the trace_clock of the machine could have changed since the trace was
   run.
