World Clock Time is a free Chrome add-on developed by Curt Norval that provides a convenient way to display multiple world clocks in a browser toolbar pop-up. With this add-on, you can easily keep track of the time in different time zones without needing to open multiple tabs or applications.

The add-on allows you to choose from a maximum of 34 different clocks from the drop-down menu in the toolbar pop-up. You can select as many clocks as you need to display. Before adding any clock, you also have the option to set the daylight-saving value, which can be -1, 0, or +1 depending on the time zone.

The toolbar pop-up is fully customizable and can be dragged around to your preferred location on the screen. All changes made to the clock selection and settings will be automatically saved to memory, so you don't have to worry about losing your preferences.

By default, the add-on adds 9 clocks to the toolbar pop-up, but you can easily remove any clocks by clicking on the cross sign next to each one. The remove button at the top-right corner allows you to remove all clocks at once if needed.

With World Clock Time, you can efficiently manage and keep track of time in different parts of the world, making it a valuable tool for frequent travelers, remote workers, and anyone who needs to coordinate with people in different time zones.
