Are you in the Yahoo! directory? If you are then what you have as your description should stay the same forever. If you are talking about the web page matches then these are provided by Google. You may hear it called Yahoogle. It will be the same stuff as google.com, Yahoo! is just using their results.
>>will it list exactly as in google?
If you are talking about yahoogle results then Yes.
Directories will never pick up changes unless the change is your site going 404. Dmoz, Yahoo!, and other directories review your site and give you one listing. That listing will not change unless you work for it with an editor.
