TclockEx enhances the standard taskbar clock in NT-based operating systems, by displaying additional information without the need to right-click.
My Windows Server 2003 displays ddd, dd MMM yyyy HH:mm:ss, but you can make it display almost any date / time format imaginable.
Additional features include a popup calendar, clipboard interaction, resource and CPU monitoring, user-definable
display elements, Internet time, and customizable color and font options.
Download TClockEx.EXE and double-click to install it.
NOTE: TclockEx configuration information is stored in the registry at HKEY_CURRENT_USER\Software\TClockEx. If you elect to Load automatically when Windows starts, it uses the Tclockex Value Name, a REG_SZ data type, to store \<Install Folder>\TCLOCKEX.EXE at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run.
