Does Time exist? -- catchphrases and concepts

This paper lends perspective to the media catchphrase that <time does not exist>. To show how phrases such as this should be interpreted, we formulate some of the most important questions that arise in discussions about time in physics. We start by analyzing Newton's objective view on time and explain how entropy gives it a direction. After that, we discuss how relativity distances us from Newton's views, while quantum theory brings us closer to the Newtonian view. The arguments are presented in such a way that they can be followed and checked by anyone who studies the theories involved - be they undergraduate physics students or otherwise.
