It means that QueryPerformanceFrequency failed:

Looking at the doc page for it, it looks like it means that your hardware
doesn't support a high-resolution performance counter. I should probably
improve TickDuration's docs on that.

If all you need to do is generate one, and you're on Linux, then uuidgen would
do it, and I guess that you'd use libuuid if you wanted to do it
programatically. But I have noe idea what you'd do on Windows.
