If you create text on a layout and include the characters // it will automatically show the current date. This works, of course, on report footers, etc, as well. Does that do what you want? Another way of extracting the date is to use the function Get ( CurrentDate ). You could also trap that as a $Variable to place wherever you want.
You can also define date fields that automatically enter the current date when the record is created and also you can have the date auto-entered when the record is modified in some way. These are options you can select for a field on the auto-enter tab in the field options dialog.
