George and Mathieu,
I am fine with switching this to relative time, since it is relative in
ns-2 and might make for a more readable port of code, and since relative
event timing is probably more frequent than absolute.
This was suggested also by tommaso originally in this thread; forgive me
for losing track if there was a reason cited to move to absolute.
