Table 2 lists some of the SAS date and datetime informats available to read date, time, and datetime values. For a discussion of the use of date and datetime informats, see Chapter 3, Working with Time Series Data. For a complete description of these informats, see SAS Programmers Guide: Essentials.
For each informat, Table 2 shows an example of a date or datetime value written in the style that the informat is designed to read. You can specify the width of each informat by adding w. For informats that include second values, you can specify the number of decimal digits for seconds by adding d. Table 2 shows the width range allowed by the informat and the default width. The date 17 October 1991 and the time 2:25:32 p.m. are used for the example in all cases.
