In the digital age, each of us has his own demon, hidden behind a seemingly random set of zeros and ones in the memory of your phone or computer. He manages the time of everyone who has given himself into the arms of the demon, known as Cron.

Unlike human beings, he never sleeps, doesn’t forget anything, monitors your every step and constantly whispers to you: "Don't waste your time!".

The software utility cron is a time-based job scheduler in Unix-like computer operating systems. Users that set up and maintain software environments use cron to schedule jobs (commands or shell scripts) to run periodically at fixed times, dates, or intervals.
