Once you’re done customizing everything, you can close the app. There’s also a Time Format tab which offers more options than Windows 10 does by default. More importantly, you can change the color of the text and even add a background color to it if you want.

You can change the font, the size, apply bold or italic styles, increase line spacing, change its size and position, etc. Run the app and go to the Clock Text tab if you’re only interested in customizing the system tray clock.

T-Clock also adds a calendar and lets you set alarms, and timers, but if that’s not something you’re interested in, you never have to be bothered with the feature. T-Clock is a free, open-source app that lets you customize the system tray clock.
