Making a continues counter.

How do I make counters like this? Using anything? Javascript, php etc... But I want it to be displayed the same to everyone and count up like so much every second.

I'm making something similar to this website.

http://usdebtclock.org/ (But I don't want flash.)

Except it is not going to be debt counter.

Thanks.

 

You'll be able to use JavaScript timer events for this.

javascript is the simplest & fastest to create a timer counter
