Change the warning message for time specifications that look off by a

factor of 1000. I realized there is a bad ambiguity in

The default unit for --host-timeout is seconds (since April 2010),
so your time of "10000" is 2.8 hours.

It could be interpreted as "seconds since April 2010" which is a strange
way to specify a length of time and would be confusing if you took it
that way. I have changed it to

Since April 2010, the default unit for --host-timeout is seconds,
so your time of "10000" is 2.8 hours.

@ -117,7 +117,7 @@ o [Nmap, Ncat, Nping] The default unit for time specifications is now
Some sanity checks have been added to catch what looks like an
attempt to use the old millisecond defaults. For example,
--host-timeout 10000 yields
The default unit for --host-timeout is seconds (since April 2010),
Since April 2010, the default unit for --host-timeout is seconds,
so your time of "10000" is 2.8 hours. If this is what you want,
use "10000s".
QUITTING!
