I have never heard of a time daemon using this port for anything. If the banner it yields resembles that of a time server, it may cause nessus to report it as such. The fact that it does doesn't really prove anything, as it is also a common tactic to make a rootkit yield a known banner in order to subvert suspicion.

That is probably very likely. This device (system) is also most likely quite old, and an attacker may have even exploited a different service to gain access, then disabled it.

The system is clearly a security risk, and, in my opinion, most likely compromised.
