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 .
Developers using newer libraries (like Qt 6 or recent Python/Rust versions) encounter this because those toolkits have dropped Windows 7 support to utilize newer system APIs. Proposed Solutions and Workarounds getsystemtimepreciseasfiletime windows 7 upd
. It was introduced with Windows 8 to provide UTC-synchronized timestamps with a resolution of less than 1 microsecond. If you're doing high-resolution timing on Windows, you've
Ensure that your system time is synchronized with a reliable NTP server. The precision API respects system time adjustments. Proposed Solutions and Workarounds
If you are seeing an error like "The procedure entry point GetSystemTimePreciseAsFileTime could not be located," it usually means a modern application or toolchain (such as MSVC v145) is trying to run on an unsupported system. Potential Solutions and Workarounds
