8 Using Clocks, Timers, and Signals in Linux

In this chapter, we will commence by exploring the various timers available in the Linux environment. Subsequently, we will delve into the significance of the clock epoch and delve into the concept of UNIX time. Following this, we will unveil the methodology for employing POSIX in Linux to precisely measure time intervals. Transitioning further, we will uncover the realm of std::chrono and examine the capabilities that C++ offers for effective time-related operations. Our journey then progresses to a comprehensive examination of duration, timepoints, and clocks as delineated within the std::chrono framework. Venturing onward, we will acquaint ourselves with the diverse array of clocks at our disposal ...
