Counter script

Hi, I have a plain html page and need a counter to add to my page that works as follow Numeric Counter This counter will be inserted multiple times on same html page, and each counter will work with different parameters. Counter start working at DD:HH:MM:SS Automatically increase number every hh:mm:ss Counter will stop increasing each day between hh:mm:ss to hh:mm:ss Counter will stop increasing permanently on the dd:mm:yyyy - hh:mm:ss Counter text can be modified (size, font type, color) Counter text should always be center (see pic1 attached) If someone check the page source code i do not want he/she understands that this is just a programmed counter. I want to give the feeling that this counter is connected to some sort of db.
