The "Hybrid" fallback above assumes the system clock is not adjusted drastically while the application is running. If the user changes the system clock manually or if the NTP service performs a large step adjustment, the calculated time will drift from the real wall clock time until the application is restarted. For most logging and duration measurement tasks, this is acceptable. getsystemtimepreciseasfiletime windows 7 upd

Purpose
GetSystemTimePreciseAsFileTime is a Windows API function introduced in Windows 8 to retrieve the current system date and time with high precision (sub-microsecond accuracy). Modern applications—particularly those built using Visual Studio 2015 or later—use this for precise logging, networking, and performance profiling. For most logging and duration measurement tasks, this
