DateTime value.

If the system 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 HEAT.
If the return value is not a valid date, the function returns the last day of the month. For example, if today is May 31, 2015, $(Last3Months()) would have returned February 31, 2015, but because that is not a valid date, the function returns February 28, 2015 because that is the last day of the month.

$(Last3Months())

If today is April 10, 2014, this function it returns the DateTime value for January 10, 2014.
