nmap result : what does "uptime" suggest?

If I nmap a host, after that it outputs an "Uptime" also. What does it suggest, is it trustworthy? Does it offers proper times?

Uptime is the moment that the system has actually been "up" and also running. So, an uptime of 100 hrs suggests the equipment has actually been running non - stop for 100 hrs.

Nmap presumes the uptime of the system. According to the Usage and Examples web page :

The uptime hunch is classified a "hunch" due to the fact that numerous variables can make it entirely imprecise.

I take that to suggest it is not trustworthy. It can be handy, though.

Some OS is usage uptime of the equipment as a base of series numbers in particular packages. That is practically a details leakage, yet they do it anyhow for in reverse compatibility is purpose. So these instances, uptime observed by NMap is in fact fairly exact.
