TimeCorrect

Ever unsure if your server's system time is incorrect? Use a host that is a little incompetent but cheap? Then this plugin is for you. On start it'll check what your server's time offset is. If your server is too far from reality, it'll alert and let you know how to fix it!

Disclaimer: I'm barely a Java developer so this plugin probably isn't the best way of doing this. I just was curious if it was possible.
