For future videos, I'll recommend avoiding redundancy. Redundancy makes this video longer than necessary. If you deliver good info and keep it short, your video will be twice as good. Please consider this little advice. I'm subscribed.
It's called a real time clock device,..Once you have a super stable time base, by a temperature controlled crystal oscillator,.. You now have a way to measure the propagation of the real time involved in factions of a second , minutes or hours of a day time , in real hours or even the number of days,weeks or months of time. So with a stable time base that has very little in the way of deviations, You can now know where you are , or how much time it will take to perform a specific operation or calculation of a function. All electrically controlled robots or computers have to have a "super stable time base",... to be able to be on target or be able to sync up to the external signals that are needed in order to help to match up with other external devices in the real world that we live in.
