Yes, if you are on Windows and need microsecond-resolution timing or sub-millisecond sleep precision. The package is stable, permissively licensed, and has no known vulnerabilities. However, expect no active maintenance or updates; dormant status means community support is limited. Not applicable on non-Windows platforms.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Windows-only; requires Python 3.7 or later and a Windows OS (wheels provided for win32 and win_amd64 only).
- Medium friction: platform-specific compiled wheels for Windows only (cp37–cp312, win32 and win_amd64).
- Dormant maintenance (last release 2023-10-08, last commit 2024-10-09); no active development but repository not archived.

What it is and what it does
win-precise-time is a Windows-only C extension that provides microsecond-resolution time measurement and sub-millisecond sleep precision, addressing a Windows-specific limitation where the builtin time.time() offers only ~15ms resolution. The package exposes two main functions: time() retrieves the current timestamp using GetSystemTimePreciseAsFileTime, and sleep() implements a more precise sleep by using SetWaitableTimerEx without requiring system-wide timer resolution changes. Both functions are implemented in C and perform comparably to the builtin time.perf_counter(). The package has no runtime dependencies and supports Python 3.7 through current versions on both 32-bit and 64-bit Windows.
The package is useful for Windows developers who need accurate timing for benchmarking, performance profiling, or real-time applications where millisecond-level jitter is unacceptable. It is production-stable but dormant; the last release was 2023-10-08 and the repository shows no active development, though it remains unarchived and free of known security vulnerabilities.
Use it for
- Benchmarking and profiling Windows applications where builtin time.time() resolution is insufficient.
- Real-time or latency-sensitive applications requiring sub-millisecond sleep precision without global timer changes.
- Performance testing frameworks that need accurate microsecond-level timing on Windows.
- Game engines or multimedia applications on Windows requiring precise frame timing.
- Replacing time.time() and time.sleep() in code when running on Windows to avoid precision loss.
