Handling Time Zones in Ecto for Event Dates

The article explores the complexities of effectively storing event dates along with their respective time zones in a database. The author highlights initial attempts at using PostgreSQL's TIMESTAMP WITH TIME ZONE type, which, while seemingly convenient, actually converts timestamps to UTC and loses the original time zone. As a solution, the author tried storing time zone information in a separate column, which, although it retained the necessary data, complicated query structures and management. The author then presents a final, hybrid approach that involves using a 'wall clock' timestamp along with separate time zone data and UTC conversion, allowing a more accurate representation of event times while addressing the fluid nature of time zones. This method captures both the user's provided time and the necessary contextual information for correct processing.
