Time zones for Windows, free and open source
A world clock for Windows made for working with people in other time zones. Add the cities you work with and see them side by side. Type a time or scroll over any clock and every city converts at once. The meeting planner shows the hours when everyone is inside working hours, and there's a live day and night map. Free and open source (MIT), no ads, no account, and the app sends nothing anywhere. On the Microsoft Store, or try the real app in your browser first.
Open World Clock is a free, open-source application for Windows that allows users to manage time zones by displaying multiple city clocks side by side. It features a meeting planner to identify overlapping working hours and a live day/night map, with no ads or data tracking.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
