Eusing Clock is a stylish and configurable desktop gadget with a range of applications.
You can use it as a simple clock, of course. By default the program displays the date, time and day of the week, and the unusual design - coloured meters to represent seconds, minutes and hours - make it an eye-catching addition to your desktop.
You can use the program to monitor the time in multiple time zones, just by adding as many extra clocks as you need (up to 128).
Need an alarm? You can set it in a click or two, using the default sound or your own custom audio file (although it needs to be WAV format).
Surprisingly, the alarm is a per-clock, not a global setting, so you can have 128 alarms in total.
What's more, alarms don't have to just play a sound. Eusing Clock can also display a message, execute a file, and lock, shut down or restart your PC.
There are plenty of configuration options, too. You can set the clock size, colours, date and time format, whether it's "always on top" of other windows, and more.
