If you're doing high-resolution timing on Windows, you've probably encountered GetSystemTimePreciseAsFileTime . It provides sub-microsecond precision (typically ~1 µs) using the system's or RDTSC . static bool initialized = false

– High-throughput transaction log need microsecond precision to resolve ordering across threads.

// Helper function to get the function address dynamically FnGetSystemTimePreciseAsFileTime TryGetPreciseFunc() static FnGetSystemTimePreciseAsFileTime pFunc = nullptr; static bool initialized = false;

This means that in a fresh, out-of-the-box Windows 7 SP1 installation, the function is in kernel32.dll . Calling it will result in a runtime error (procedure not found).
