Handling Timezones in Phoenix LiveView Forms

Andrew Timberlake's article dives into using the datetime-local input type in Phoenix LiveView applications. He describes how this HTML input allows users to select date and time, but returns it in the user's local timezone. To overcome this, Andrew introduces a custom component and hook to capture the user's timezone and explains how to use this information in the LiveView backend. He provides detailed code examples, including the component definition in Elixir, and JavaScript hooks to set the timezone. Additionally, he explains how to handle the submitted date and time, accounting for the user's timezone on the server side.
