Overview

BrowserTimezoneRails is a Rails engine designed to automatically set the application timezone based on the user's browser configuration. This capability enhances user experience by displaying timestamps in the user's local time, making it particularly beneficial for applications that deal with time-sensitive data. The setup process is simple and requires no extensive configuration, allowing developers to focus on building their applications without worrying about timezone discrepancies.

By leveraging modern JavaScript features and cookie management, BrowserTimezoneRails ensures that every request is accurately aligned with the user's local timezone. However, it's worth noting that there are limitations, particularly with Internet Explorer, which may affect some users.

Features

Easy Installation: Simply add the gem to your Gemfile, and you're ready to go with minimal setup needed.
Automatic Timezone Setting: The gem sets the Rails timezone based on a cookie that stores the user's browser timezone, automating the process for each request.
Modern JavaScript Utilization: It employs the ECMAScript Internationalization API to determine the user's local timezone accurately.
Long-Lived Cookie: The timezone cookie is set during each page request and has a lifespan of 365 days, ensuring persistence across sessions.
Thread Safety: It utilizes the Rails Time.zone method, which is designed to be thread-safe, making it suitable for multi-threaded environments.
Minimal User Impact: The only caveat involves the first request from a user's browser, which might not have an immediate timezone set, but this is typically not an issue.
Testing Support: Development and testing can be executed effortlessly using RSpec, promoting a smooth development workflow.
