Handling time in Linux
Timing is an essential aspect of any computer system, and Linux is no exception. In Linux, there are different types of timers available, each designed to handle specific tasks and requirements.
These timers can be used to measure the execution time of programs, schedule tasks, trigger events, and more. In this section, we’ll explore the different types of timers available in Linux and how to use them effectively.
