C Specification

To convert from XrTime to a Windows performance counter time stamp, call:

XrResult xrConvertTimeToWin32PerformanceCounterKHR(
    XrInstance                                  instance,
    XrTime                                      time,
    LARGE_INTEGER*                              performanceCounter);
