IMP all studnets please read ! [Csci551-talk] Assumption: When to start timeout

[Affan, Syed]

Sorry for the delayed response but it was a good question and needed
some thought. 
The correct approach has got to be to start timer as soon as you buffer
the packet. But the log time should be when it is actually sent. I know
this can create pathological scenarios, but this is most realistic and
we can test your implementation through simpler scenarios :)

Thanks.
Affan
