At my place of employment, I work a great deal with somewhat complex hierarchical data as part of our measurement and analysis software. Thus, recursion and I have become rather close friends over the last few years. While rewriting an old website, I needed to turn a set of four relational tables into a hierarchical data structure.

Also, many applications are not locale aware or were not designed to be deployed in an environment where locale issues were not considered important. Because of this it is extremely important to know the date formats in use for input and output when building applications that will integrate with other systems or databases and to handle these formats explicitly.
