Handling date and time in our applications can be a complex task with many nuances. How should we handle date time? Should we store local time zone or UTC? Should we store dates and times separately? Should we use Unix time? These are all valid questions and there isn't always a one-size-fits-all solution. In this talk we will take a look at the challenges that date and time present to us, the different scenarios we might run into, and how we might solve them in our applications. We will look at the pros and cons of different approaches and see which approach might be best in various circumstances.
