Definitions
|
||||
===========
|
||||
|
||||
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 Specifiction 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."
