## Review summary

Users report that the add-on can correctly change the browser's time zone with instant updates and can be useful for services like AWS, but reliability is inconsistent. It works well for some sites and tasks, yet breaks many others and can cause date-related issues. It also interferes with certain sites (YouTube, hCaptcha) and even opens ads/tracking pages on install. DST handling is incomplete. Overall, it’s handy for testing or per-site display, but not dependable across the web.

### Pros

- Changes the browser's displayed time by adjusting the timezone parameter with immediate effect across sites.
- Generally works well for many users and scenarios, with multiple reviews noting it functions as intended.
- Useful for displaying a different time for specific services (e.g., AWS) or for testing time-related behavior across websites.

### Cons

- Inconsistent across websites: works on some sites but breaks others, making reliability low overall.
- Breaks a significant number of websites or causes date-related issues beyond simple timezone changes (e.g., date pickers showing incorrect dates, 'Invalid Date' errors).
- Interferes with certain sites or checks (e.g., YouTube, hCaptcha) and can block or disrupt functionality.
- Opens an ad/tracking page on install and uninstall, which is undesirable for many users.
- Does not properly account for DST, leading to improper time handling in some scenarios.
