Date And Time Functions In SAS

Date and Time functions in SAS are considered numeric variables, but they have several special properties to be aware of. Dates or Times in their dataset, SAS internally records datetime variables as integers. This helps to simplify the computations when computing the differences between dates. By default, SAS date and time variables are printed using the SAS internal values, rather than a human-readable date format. However, dates can be displayed using any chosen format by setting the format in a data step or proc step.
