-Resolution
-----------
-
-The resolution is the smallest difference between two timestamps supported by
-the format used by the clock. For example, clock_gettime() uses a timespec
-structure which has two integer fields, tv_sec and tv_nsec, so the resolution
-is 1 nanosecond.
-
-Precision
----------
-
-The precision is the effective smallest difference between two timestamps of the
-clock. It does not reflect the stability the clock rate. For example,
-QueryPerformanceCounter() has a good precision but is known to not have a steady
-rate.
-
-
-Monotonic
----------
-
-A monotonic clock cannot go backward. It may give the same value for two close
-reads depending on the clock resolution.
-
-On Linux, CLOCK_MONOTONIC is a monotonic clock but its rate is adjusted by NTP.
-
-Steady
-------
-
-A steady clock is a clock with a stable rate.
-
-The `C++ Timeout Specification
-<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3128.html>`_ uses the
-following definition: "Objects of class steady_clock represent clocks for which
-values of time_point advance at a steady rate relative to real time. That is,
-the clock may not be adjusted."
