Counter, Like a Clock

I need a simple code that will work on a php hosted website that was developed in DreamWeaver. What I want is something like a clock. I want it in bright red to look like it is lit up. I want this to count up. I want to be able to adjust the numbers for it. I believe that it will start at somewhere around 1,500,00 and count upward. This is the number of feet. the number will increase by .83 per minute every minute of the day or continuous. In the course of several months, this number might be off, so I will need to be able to adjust the number. Like I say, this is a simple code could probably be done as a javascript. It is much like a clock and will count up and allow me to change the numbers if needed and will increase by .83 every minute.
