If you select the Date and Time checkbox, you will be given two options: Update automatically and Fixed. The Update automatically option means that the date and time will updated every time you open the presentation, which will save you the time and effort involved in updating it manually. The Fixed option means that, even if you open the presentation a month from now, the date and time will be fixed to the time when you created the header and footer.

If you select Update automatically , you will be given a number of different formats for displaying the date and time, as shown below in the screenshot. Make a selection that best fits the format of your presentation.
