I may be wrong, but isn't there an almost unlimited amount of ways that you could determine wallclock time? Any kind of networking access can get it (with enough samples, you can get some crazy precision over even the most inconsistent networks), and really any kind of I/O could be abused when combined with another exploits. And if your permissions system doesn't allow I/O, is there really a lot that your program can do?
