One of the strengths of Linux is the vast number of small, niche utilities that are made available under an open source license.
One of the most basic utilities supplied with any operating system is a clock utility. The clock typically resides in the taskbar / menubar, showing the current system time. Nothing very exciting there.
multiClock is software that lets you track the current time in major financial centres around the globe. It’s free and open source software.
Installation
We evaluated multiClock using Manjaro, an Arch-based distro. We installed the software using Flatpak, an open source containerized package format similar to Snap. While Snap relies on a central repository for software, Flatpak can be installed from different sources. The primary source is Flathub.
We installed the software from Flathub.
$ flatpak install flathub io.github.r_sergii.multiClock
In Operation
By default, the program displays the clocks in a vertical alignment with all cities selected. But it’s easy to change them into a horizontal alignment just by resizing the window, as well as the ability to unselect some of the cities.
Here’s an image of the program in action. We’re only showing some of the cities.
The software is designed to help Forex traders who are away from their trading monitors. The interface is very simple, it displays a country flag for each city. The software takes into account daylight saving time.
There’s also internationalization support.
Summary
multiClock only saw its first public release a few days ago. The project is off to a good start. We’d like the ability to add additional cities which would extend the usefulness of the program to other individuals besides Forex traders. And the ability to rearrange the cities would also be a great improvement.
We’ll be adding multiClock to our roundup of the best free and open source clock applications.
