After a lot of work restructuring the panel to be able to reliably get a response to a command it runs, I was able to throw together two new commands for the ServerAI.
Time? (or asking "what time it is/is it daytime" etc... )
This will let you know the time of day in game as well as a more easy to read string like "Day" or "Night", great for when you are mining.
TPS? (Ticks Per Second)
This command will take a sample of how fast the server is running compared to what it should be. (20.0tps) It will show the tps along with a color representing how much load the server is under.
Why it took so long
At first glance it looked like an easy thing to do, but as soon as I started, it was very clear it wasn't. It's easy to run a command and forget about the result, but keeping track of the output is much more difficult. You need to know whether or not it succeeded, then get the results back to the place that called on the command without stopping the whole program, all with the knowledge that it could fail at anytime, not respond, give something completely different or even come out of order.
