T-Clock Redux

GCC(MinGW-w64) Build Status Coverity Status MSVC Build status (click picture below for full size) clockshowcase
T-Clock Redux is an enhanced fork of Stoic Joker's T-Clock 2010
with ISO week number support, bug fixes and the ability to use Windows' default calendar and tooltips.

T-Clock (called TClock), originally written by Kazubon in the early 90's, was a popular classic that was on the edge of extinction when Windows started going 64bit. ... Stoic Joker simply chose not to let that happen. And now it's up to us to continue their efforts.

If you don't mind to read lots of text, and want to know more about T-Clock and its history: check this page out! (thanks Gregg)

What's that _vc2010 build?

  • As of 2018, all new releases will be build with GCC instead of the Visual C++ 2010 compiler. So the previously known _static builds are used instead and for compatibility reasons, _vc2010 archives will still use the old compiler and are meant for advanced users.
  • Requires: Microsoft Visual C++ 2010 Redistributable (install both 32bit vcredist_x86 + 64bit vcredist_x64 on 64bit OS)



  • GPLv2 ? (license is currently unknown, needs further research)


Highly configurable Windows taskbar clock
