reference.py reads time.clock_gettime_ns(time.CLOCK_MONOTONIC) to vary extra_in across signing iterations. Both symbols are documented "Availability: Unix", so `python3 reference.py` raises AttributeError on Windows. time.monotonic_ns() is the portable monotonic clock CPython documents for measuring elapsed time, available on all platforms since 3.7. Not tested on Windows.

bip-0327/reference.py's self-test readstime.clock_gettime_ns(time.CLOCK_MONOTONIC)forextra_in. Both symbols are documented "Availability: Unix" in CPython, sopython3 reference.pyraisesAttributeErroron Windows.time.monotonic_ns()is the portable monotonic clock CPython documents for measuring elapsed time, available on all platforms since 3.7. It returns the same nanosecond int, so.to_bytes(8, 'big')is unaffected.Not tested on Windows; verified against CPython's platform-availability docs.
