You could have downloaded TClockEx 1.4.2 from our software library for free. TClockEx relates to Office Tools. The actual developer of the free software is Dale Nurden.
From the developer:
TClockEx enhances the standard Windows taskbar clock, adding the ability to display the date, time and lots of other information in any format you like. TClockEx is highly customizable, from the format to the font and colour, and even the tooltip information. Many people have wondered why this wasn't built into the standard clock to begin with.
I originally wrote TClockEx out of frustration with not being able to see the date easily.
You may want to check out more software, such as TurboNote+ or Reminder Commander, which might be related to TClockEx.
