Monoclock is a Python module that provides access to the monotonic clock on POSIX-like OSes that have librt.

Compatibility: tested on CPython 2.6.5, CPython 2.7, pypy 1.3, and pypy 1.4.

Install: python setup.py install

Run the tests: python run_tests.py

import monoclock
t = monoclock.nano_count()
print t

If you want seconds, divide t by 1e9.

If you're having trouble with monotonic clocks, see:

• http://code-factor.blogspot.com/2009/11/monotonic-timers.html

• Factor's source code.

• Chromium's source code.

• Windows support.

• Solaris support (does it work?).

• Expose CLOCK_MONOTONIC_RAW (which is not adjusted by NTP).

• Support buggy AMD chips, or expose a probablyBuggy() function that returns True if the monotonic clock is unreliable.

  Note: Chromium's base/time_win.cc just disables use of the monotonic clock on Athlon X2 CPUs with if (cpu.vendor_name() == "AuthenticAMD" && cpu.family() == 15
