"""Dates and Times.

@see: https://docs.python.org/3/tutorial/stdlib.html#dates-and-times

The datetime module supplies classes for manipulating dates and times in both simple and complex

ways. While date and time arithmetic is supported, the focus of the implementation is on efficient

member extraction for output formatting and manipulation. The module also supports objects that

are timezone aware.
