What does the INTNX function output when it calculates a date?

The INTNX function is designed to work with SAS date values and is primarily used to manipulate dates by shifting them forward or backward in time based on a specified interval. When INTNX calculates a date, it takes into account an original date along with a specified number of intervals and an interval type (such as days, months, or years).

The output of the function is a new date that reflects this adjustment, meaning that the resulting date is altered by the specified number of intervals. For example, if you used INTNX to move a date forward by one month, the function would return a date that is exactly one month later than the original date. This characteristic of the INTNX function makes it particularly useful for date calculations in time series analysis, reporting, and various data management tasks where an understanding of date relationships is essential.

Thus, option B accurately describes the behavior of the INTNX function when it processes a date, confirming that the output is indeed a date affected by a set number of intervals.
