Why don't we know what time it is? Part 1 | Watch and Learn #93

Let's embark on a little journey today. . . What time is it? Well, the truth is, we do not know. We only know what time it was, so we actually do not know what time it is now. But, how do we know what time it was? The answer might surprise you!

Thanks for watching.

As an engineer, I find this topic and your presentation excellent. Please do more.

Once I started wearing watches again, I suddenly realized that I once again have access to "times" that many never have. Like "quarter to eleven." If you read your phone to check the time, you don't have quarter to eleven. You have 10:45. WIN! It's like another dimension. A grown-up dimension. LOL.

I simply love this topic 😀
Please, please keep those kind of video coming👍🏻

As a fellow engineer, I also do not really understand physics... but seriously, great video. I remember watching these "watch and learns" many years ago. I'm glad you still make them from time to time. They truly are a service to the youtube watch space.

“Does anybody really know what time it is? Does anybody really care? About time? If so, I can’t imagine why. We’ve all got time enough to cry.” - couldn’t resist. That was one of my dad’s favorite songs. Thanks for bringing back fond memories for me. Amazing how much of the watch collecting journey is connected to memory and emotion and connections between people.

Currently wearing my Skyhawk which sets itself via radio every morning at 2am. Loved this video, thank you Marc 👍🏻

“Does anybody really know what time it is.” Great song by Chicago.
All I know is my G Shock Atomic watches all have the same time. 😂

Marc - love this, thank you. I look forward to more of this kind!

Marc, a Superman TV episode from the 50's had him going to the Atomic observatory people in Colorado to speed up the time to flush out criminals who were running out the Statute of Limitations- waiting for their clock connected to the observatory to pass midnight. They were shocked!!!

While listening to my shortwave radio when I was a teenager, I discovered WWV in Colorado and CHU in Canada.
I was fascinated by the time signals that were broadcast over the airwaves and would set my Mickey Mouse watch to those signals.
I still rely on the atomic clocks to this day. Yes, they are not perfect but it’s good enough for me.
Thanks for the post!

Mark, so happy to have you back doing Watch and Learn, thanks!

As the video reminds you, Marc’s love of time (& watches) is genuine. As a non-STEM person, thx! I learned something! 🤯

In computer networks time is a big deal from a security standpoint. There will potentially be a lot of clocks synchronized on a network. Latency, distance, congestion, and packet collision percentage all play a role in these updates. A pristine atomic clock is stratum 0, and only supplies time requests to a limited number of stratum 1 clocks. Stratum 1 supplies stratum 2, 2 supplies 3, and so on. It's amazing how critical something as seemingly simple as time is regulated and maintained behind the scenes of things we use everyday and take for granted.

I was reminded of a song by the band Chicago - “Does Anyone Really Know What Time it Is?”

The sun, moon and stars are all we really need.

It makes me happy to know that there's someone else that cares about this.

Answer to your question, time passes slower when you're closer to a massive object, so time is passing slower at lower altitude.

[Gary-ibdz]

Thanks Marc. I like when you put these informative videos.

[tylerjames]

love the watch and learn series. This is a topic that has always fascinated me - so thanks for the great presentation! Looking forward to the next installment.

I’m amazed how many engineers have a fascination with time and the mechanical marvel that track it for us. Thanks Marc

Way to ruin the joke about finding a guy wearing a quartz so he can tell you what time it is 😆
