Some doubt about news section URL

[NorbertoMM]

I have a simple question, I have a website and i want to create a news category. I want to know what is the best way to create a url friendly for this category. I was looking around for news website like New York Times, and others, they use a format like this for the url

http://domain.com/year/month/day/category/ etc.

My question is about the use of the date in that format, like subdirectory, can somebody explain me about it. Any reason to use this format?

What is the diference between using this format like: http://domain.com/news/çategory/article-date-id.html and this one use for the new york time shown before.

Wich one will be work better?

Thank You so much  for your help

Neither will necessarily work better. In the old days, news and blogs all seemed to use dates. Problem is that dates don't really add any value so why not just keep it keyword rich with category and article name? If you're going to submit the site as a Google News Source, you may want to read http://www.google.com/support/news_pub/bin/answer.py?hl=en&answer=68323.
