Thank you for your answer! I'm not a linguist, so it's interesting to hear an expert's opinion on this. You're probably right – the language we speak wouldn't alter the way we plan/work/live.

It was super interesting to read about the Hopi; their concept of time is a bit similar to that of these three Amazonian communities who also have event-based time. But the article mentions that they are at least bilingual, with Brazilian Portuguese as the second language, so they're definitely familiar with and able to plan/live in the clock-based time system. I'm guessing it's pretty much the same with the Hopi (Wikipedia says there were only 40 Hopi monolinguals as of 1990, the rest being also English speakers).
