In the software industry, handling dates and times in simple applications is a common and challenging problem, requiring a particular design and implementation to have the correct solution for such challenges. In addition, it becomes more difficult when you develop a system that is needed to handle international users across the globe, and each has a different timezone. In many cases, those users' countries have a daylight-saving setting that needs to be considered. Let me add some complexity to the point. According to municipalities located within their own country, countries like the USA and Canada have cities with different time zones.

Such challenges affect saving and searching dates, which affect the average application functionality, where it is a current problem that must be solved. In this session, we will explore in real examples how to handle such a problem using a full e2e REST-based Spring Boot app connected to a database.
