I really wouldn't use VBScript, or any other command line based batch processing language for this: You would be much better off learning VB (or better C#) and creating this as a GUI app where it won't waste so much processing time and will flicker less.
But ... spaces are important:
echo.
echoTime: %time%
echo.
echo Date: %date%
Without a space between "echo" and "Time" the system looks for a command "echoTime" and doesn't find it.
