 ## Explanations
 
 This project works on the way `git` records commit. Whenever you commit something, `git` puts an `Unix Timestamp` on it to record when you committed it. An [`Unix Timestamp`](https://www.unixtimestamp.com/) is the way computers store the current time. An `Unix timestamp` is a `32-bit` number which stores the number of seconds that has passed from January 1st, 1970 at UTC, the `Unix Epoch`.
