What is it?

Jans is an unusual NTP server: it can return the systemclock time (and just that) but it can also return blatantly incorrect time. It is an NTP test-tool.

This program can be used to: You might want to return invalid time when for example you've been in and left it and want users who still use your server to forcibly stop using your server.
