NOTE: The default download is highly outdated. New version works with Windows 10 21H2

In case you missed it - like I did - the default release on the main github page is very old and won't work, but there is a newer version.
You'll get the newest version by expanding the "Releases" section: https://github.com/White-Tiger/T-Clock/releases

Works with W10 21H2 (19044.3086).

Have a nice day and enjoy proper clock on Windows :)
