Inserting Current Date and Time Information
To insert the current date and time in your document, choose Insert > Date and Time in the menu.
The information can be added as an individual text field, or inside a text box. You cannot edit it directly. To update the information, double-click on the Date and Time field.
To change the text formatting, use the tools in the Text tab of the Inspector.
To choose a different pattern for the data representation, double-click on the date and time field and select a pattern in a drop-down list.
The Format edit box lets you create a custom pattern. Symbols in the pattern replace date, month, year, and so on. For example, "yyyy" produces the current year in the format "1999," and "yy" gives a shorter format "99." For more details about time and date patterns, go to this web site:
