Why does telling the time work the same way everywhere?

That is a pretty good question, but time is essential for traveling. Therefore there needs to be some kind of uniformed time scale to say the least, to really allow for people to understand. That is one cultural barrier that cannot be put up. I'm almost certain at one time, there was another word for time. In a multitude of cultures in fact. However in this day and age, there is going to need to be something that is understood across the world. There is nothing more fitting of this element then the concept of time. There is times where people will need to travel through multiple countries and will need to know when everything leaves. Therefore this universal approach has been adopted. It is not that hard to learn, in fact it is even second nature for a lot of people. It just makes the most sense all around the world. So yeah, time is universal a lot of the time, perhaps because of travel.

Time may have been standardized but people's notion of it hasn't. There are still many parts of the world where the population cannot tell you the day, let alone the hour. Even most people who wear watches will often be late so where is the standardization?

i dint exactly understand what ur question is?
