  The error message indicates that the `clj-time.core` namespace isn't on the JVM's classpath. The classpath specifies all of the places the JVM will look to load Clojure namespaces (or Java classes).
  
  Using a dep involves specifying which library (dependency or "dep") you want to use by providing its name and other aspects like version, getting it (once) from a repository to your local machine, and making it available on the JVM classpath so Clojure can find it while your REPL or program is running. Clojure tools specify a syntax and file (deps.edn) for dependencies and handle downloading the library and adding it to the classpath automatically.
  
  Exit the REPL by typing Ctrl-D at the prompt to return to the terminal.
   
  Create a file in the current directory named `deps.edn`. This file is in the https://github.com/edn-format/edn[edn] data format, a subset of Clojure syntax. It contains a map with the well-known key `:deps` which is a map from library to coordinate:
