finalize_timings()

Finalize Nebula timings by adding total execution measurements and add times within each category.

PHP March 7, 2018

Usage

This function runs automatically, so it is not called manually. Is this incorrect?

Additional Notes

By calling this function you may prematurely end full execution timings and decrease accuracy. It’s best to let Nebula call this when it is ready.
