Worldtime is a Firefox extension designed for users who need to manage and compare time zones across different locations. This tool is particularly useful for scheduling meetings or events that involve participants from various parts of the world. It utilizes the latest IANA time zones database to ensure accurate time information, including daylight saving time adjustments for relevant regions. Users can easily view the current time, UTC offsets, and active daylight saving status for multiple locations at a glance.

In addition to providing real-time time zone information, Worldtime offers several practical features. Users can export their schedules to .ICS files, making it compatible with applications like Outlook. Additionally, it allows users to export events directly to Google Calendar and offers the option to copy schedules to the clipboard for easy sharing. This functionality makes Worldtime a comprehensive solution for anyone needing to coordinate across time zones.
