Karim,
Of course, I can not prove it, but at the time I put in the tracer support, I
was not aware of LTT's existence. I was trying to track down a timing problem
with in beta15, so I wrote this trace program that did help to solve the
problem. Apart of "similar code" (note, I never saw any of LTT's
until your message about do_gettimeofday),
these two tools, as I see now, solve different purposes.
