* What is this: 'thisInterval()' as a closure-as-callable-php-variable
*
* Explainer: imagine having a job scheduler with a production accuracy requirement to the minute..
* Now imagine desiring an easy way to loosen that accuracy constraint, for sake of easier tests..
* With an approach like this, just put the accuracy setting into configuration, e.g. .env file.
