Live dates are automatically updated, so that whenever you open the document today's date is automatically displayed. This is useful for templates such as letters where you need not remember to add the correct date.
Fixed dates are never updated. The date which appears when you first enter it is never changed. This is useful for documents you intend to return to where you need a fixed timestamp.
To add today's date to a document:
Place the caret where you want the date to be added.
Display the Inserts sub-menu from the Extra menu and choose Date.
The Insert date dialogue box will be displayed.
Choose the date format you want to use. If the Live option is selected, a live date will be entered. Click on the button for the setting you want.
The date will be entered in the format you want. If you have chosen the Live option, the date will be updated to the current date whenever you open the document. Turn the Live option off to enter a fixed date in your document as a permanent record of the date of creation of the document.
