Many people don’t have much of a choice, at least during their work week. Employees in hourly shifts usually cannot eat on the clock, so it’s breakfast before you leave, lunch on your midday break, and dinner when you get home.
The clock is just a convenient way to get a group of people to agree what “eating time” is. They would do the same without.
Which doesn't necessarily happen at the same time every hunt. There's no post-hunt retro at 1300 every day.
You're agreeing with the article that until very recently, event times were flexible and determined by processes that aren't the vibration of a piece of quartz.
I don’t think it’s accurate to say I agree with the article. Certainly clocks are a relatively recent invention. That doesn’t mean I agree with its central thesis, which I think is essentially unsupported by the various anecdotes and historical tidbits the article contains.
