Please read Writing an effective Apple Support Communities Question, it will help you understand what we need from you in order to effectively assist you.

So what do you see when you're in Safari and click on History in the menu bar? If you scroll down to the bottom, you should see Clear History. This brings up a dialog box, where you can select Last Hour, Today, Today and Yesterday, and All.

Are you seeing something else in that drop down menu?
