@gnandan better to change the base to 2.6.0RC if all good. /cc @ashish-jabble @Mohit04tomar

It would be better if define it as const

I do not think, i fully understand the rationality of the logic here. What is the need to look into lower order precision (micros second) ? to override, high order precision ? Does our need to have time precision of 500 milli second ..?

I think it is better if we stick with the time precisions.

I see we are using gettimeofday() here are some resons we should not use it https://blog.habets.se/2010/09/gettimeofday-should-never-be-used-to-measure-time.html

Here the example code with custom precision.

    auto start = std::chrono::steady_clock::now();

    // Perform some operations
    for (int i = 0; i < 1000000; ++i);

    auto end = std::chrono::steady_clock::now();
    auto duration = std::chrono::duration_cast<std::chrono::milliseconds>(end - start);

It is very debatable as to if the issue raised is a real problem. I would be very tempted to say we do not include this and close the original Jira as not a problem.
