There are different benefits to different ways of representing time, such as including the region in the time information, which is very helpful for people in foreign countries so that we can be sure of when the tweet was actually sent. For example, if I'm studying in the US and my family sends a tweet from China, not including the time in the region would make it impossible to determine exactly which “yesterday” the tweet was sent.

This was a shock to me, I didn't know much about binary, but it turns out that it has both true and false states. And I also just learned about the direct mapping of boolean types to binary, which makes the whole data analysis much simpler to compute.
