bpo-23428 modified the pthread implementation of conditional variable to use pthread_condattr_setclock(&ca, CLOCK_MONOTONIC) is available: commit 001fee14e0f2ba5f41fb733adc69d5965925a094. The change should be part of Python 3.8.

What is your sys.thread_info value? Example on Fedora 32 with Python 3.8.5:

>>> sys.thread_info
sys.thread_info(name='pthread', lock='semaphore', version='NPTL 2.31')

Sadly, the semaphore implementation doesn't use monotonic clock. See glibc issues:
