Possible bug report - nmap scan elapsed time changes into negative time

["Mark Furst" <mark.furst () clicksgroup co za>]

Hi there

 

While running a nmap scan on a huge internal network for several weeks, I noticed that the elapsed time changed into 
negative time.

 

I commenced the scan on 28 February 2011. The nmap command that I used is listed below:

# Nmap 5.35DC1 scan initiated Mon Feb 28 08:34:17 2011 as: nmap -sS -vv -p- -T4 -oA targetname-full-20110228 -iL 
targetip.txt

 

Today's date:

Fri Mar 25 09:06:14 SAST 2011

 

Thus as the scan has been running for almost 4 weeks nonstop, it should display an elapsed time of over 600 hours by 
now. When getting the current nmap stats, I get the following output:

Stats: -592:-33:-30 elapsed; 82127 hosts completed (4936 up), 64 undergoing SYN Stealth Scan

 

System stats:

Linux bt 2.6.34 #1 SMP Wed Jul 21 09:51:09 EDT 2010 i686 GNU/Linux

 

System uptime:

root@bt:~# uptime

09:09:36 up 31 days, 23:57,  3 users,  load average: 0.09, 0.09, 0.03

 

cat /etc/issue:

BackTrack 4 R2 Codename Nemesis \n \l

 

Please let me know if you can replicate the issue and confirm whether it is a bug.
