World Time Buddy (WTB) is an online app and website that helps users to easily compare time between different cities and countries around the world. It provides a simple, user-friendly interface that allows users to quickly compare times between two or more different cities or countries. The app also provides a convenient calendar view, so users can easily plan and schedule events. In addition, WTB also provides a 'time zone calculator' to quickly estimate the time in other cities on the same day. Other features include a local time clock, reminders, and a custom time zone map. With World Time Buddy, users can keep track of the time in any location quickly and easily.
No restrictions on # / cities, the drawback is that it only shows the current time and not a timeline.
Discontinued Official website and application not available.
You can add as many time zones as you wish without having to pay a premium rate.
