Family:	Function	Category:	Date and Time
Description:	Add months to a given date or datetime value.

Adds the specified number of months to a date or datetime value. This function will always return a valid date or datetime if the beginning date or datetime is valid. This function will always "roll" the years value as necessary. For example, adding 13 months will advance the year as well as adding 1 month.

Using a negative INT will result in subtracting that many months.
