Javascript And Putting Date/time On Web Page?

How can I put the date and time on my web page from an external javascript file?
I’d like the format to be like:
Wednesday, May 1, 2007 7:45:00 AM
and the time has to be constantly updated.
None of the web sites online help… they each have different ways of doing this and I am so confused!

I Need A Random Date/time Generator Program. Anyone Know Where I Can Find A Free One Online?

I want to be able to plug in a date range and then have the program pull up a certain number of random dates/times in this range. I have seen one online before, but now I cannot find it again. Thanks for your help.
