How to Achieve High-Resolution Time Measurement on Linux Systems?

Determining Time with Precision on Linux Systems

Under Windows, developers can leverage functions like QueryPerformanceCounter from mmsystem.h to achieve high-resolution time measurement. But what are the options available for Linux users?

In the Linux environment, developers have access to a plethora of tools for precise time management. Two notable options are:

• Boost Ptime Function: The Boost C library provides the ptime function, which offers nanosecond-level precision.
• POSIX Clock_gettime() Function: This function, part of the POSIX standard, provides a versatile method for retrieving high-resolution timestamps. It can be used to obtain both the current time and the amount of time elapsed since an arbitrary point in the past.

These tools empower developers to accurately measure and track time intervals in Linux-based systems, enabling precise scheduling, performance analysis, and other time-sensitive operations.
