I read somewhere a long while ago about the internal working of traceroute.
I may be wrong, but I recall that it goes something like this:
a. Source to 1st hop.
b. Back to source to print first hop (success) and time.
c. Source to 2nd hop via 1st hop.
d. Back to source ignore time to first hop, print second hop (success) and
time.
and so on.....
