# Introduction The year is 2285, and humanity has established a thriving space station orbiting the planet Mars. This research facility, known as the Martian Observatory, serves as a hub for scientific exploration and discovery. Among the many scientists stationed here is Dr. Emma Wilkins, a brilliant data analyst specializing in astronomical observations. Dr. Wilkins has been tasked with analyzing vast amounts of data collected from various telescopes and instruments aboard the station. However, the data is in a raw format, and she needs to process and manipulate it to extract meaningful insights. One of the critical challenges she faces is working with date and time information, as many of the observations are time-sensitive and require accurate date calculations. To tackle this challenge, Dr. Wilkins must leverage the powerful date operating functions available in Hadoop Hive, a data warehousing solution designed for big data processing. By mastering these functions, she can efficiently manipulate and analyze the date and time data, enabling her to uncover patterns, trends, and anomalies that could lead to groundbreaking discoveries in the field of astronomy.
