Run a job at exact time interval

Let suppose,

I have set a variable as 10 min, so what-ever time my script will run first, the job function should always trigger on 10:00 -> 10:10 -> 10:20 -> 10:30 though my script started at 10:02 or 10:08.

Similarly, the unit of time (minute, seconds and days) can be configurable and so the triggering mechanism can work accordingly.

No files, tests, or entry points are named. Start by reviewing the scheduler's existing interval behavior and the linked crontab.guru example; done means supporting fixed clock-aligned intervals with configurable minute, second, and day units, including scripts started between scheduled times.
