  There are many Clojure and Java libraries available that provide access to practically any functionality you might need. For example, consider the commonly used Clojure library https://github.com/clj-time/clj-time[clj-time] for working with dates and times.
  
  To work with this library, declare it as a dependency so the tool can ensure it has been downloaded and added to the classpath. The readme in most projects shows the name and version, such as `[clj-time "0.14.2"]`.
  
  Create a `deps.edn` file to declare a dependency using the library name and version:
