A map of the world with vertical lines marking the time zones from UTC-12 to UTC+12. It has a legend:
Wrong Time
"Natural time zones" are 15° in longitude. Land in red observes a time other than the zone it lies within. Smaller islands depict their 12 nautical mile territorial sea, for visual effect. In some cases this includes a state's archipelagic waters.

I think it's kind of dumb tbh. I imagine at certain times of the year, you will have farmers on one end of the country waking up in complete darkness, while others are waking up in broad daylight (I didn't do any actual critical thought to determine if this is actually true or not, but it seems right).
Spain more than France, but both, tend to eat later, wake up later, as a response. Farming schedules are going to be dawn till dusk, and food market/retail hours would tend to follow. Stock market traders will match sleep/work schedule to market hours.
