TClockEx is a simple and old system clock that is intended to replace the clock that comes with Windows. Once installed, the clock appears in your system tray just like the Windows clock and displays the time and day of the week in the format you want. You can also select text and background color and customize the font. Even so, the clock is not really attractive and looks rather old. The clock also comes with a calendar that can be moved all around the desktop and it is pretty customizable. However, just like the clock, it isn't really attractive nor useful, since it lacks many other important features like reminders or alarms that could stand for a difference with the Windows clock, and would make the program worth a try. The only difference I found is the ability to copy the time and date of the clock to be used on another programs, but it is not a big deal since many text processor applications, like Word, come with this option.
All in all, TClockEx is a simple and old clock intended for old operating systems that certainly doesn't deserve a try unless you use a very old computer.
