Detailed Description

Android, chrono-compatible, suspend-aware clock.

Linux steady clock is represented by CLOCK_MONOTONIC. However, this implementation does not work properly for long-running clocks that work in the background when the system is suspended.

SuspendAwareClock uses CLOCK_BOOTTIME which is identical to CLOCK_MONOTONIC, except that it also includes any time that the system is suspended.

Note: In most cases, CLOCK_MONOTONIC is a better choice. Make sure this implementation is required for your use case.

Type traits and static members.

These type traits and static members meet the requirements of a Clock concept in the C++ Standard. More specifically, TrivialClock requirements are met. Thus, naming convention has been kept consistent to allow for extended use e.g. https://en.cppreference.com/w/cpp/chrono/is_clock
