The number of weeks to go back.
If you enter a negative number, the function returns the local date and time for a date that is a certain number of weeks in the future, based on the local time of the current session.
If the application has to display the return value, it implicitly converts it to text, thereby allowing the display format to change depending on your culture code. See Available Languages and Cultures for a list of the culture codes used by Neurons for ITSM.
If today is April 10, 2014, the function returns the DateTime value for March 20, 2014.
