/*
Summary:
- Prefer to work directly with concrete types
- Leads to a simple and easy to understand code
- Abstractions (interfaces) can unnecessarily complicate your code
- Separating responsibilities is critical
- Timestamp type can represent, store, and print a UNIX timestamp
- When a type anonymously embeds a type, it can use the methods of the embedded type as its own.
- Timestamp embeds a time.Time
- So you can call the methods of the time.Time through a timestamp value
