This was seen in an environment an in-memory SQLite database and no optional dependencies installed (virtual environment with Trac and Genshi only).

Are you using Windows 7? Windows 7 has still has low-resolution system time issue. GetSystemTimePreciseAsFileTime() is available since Windows 8 and Windows Server 2012. See comment:2:ticket:12311.

Yeah, it's Windows 7. That explains why I didn't see the error on every execution. I guess we can ignore the comment:1 errors in that case.

I plan to move to Windows 10 soon, but my company is lagging so I have to do development in a Windows 7 VM still. I don't have enough room on the SSD of my Mac Pro to also store a Windows 10 VM. Maybe I'll try running a Windows 10 VM off an external disk.
