Notes

The ARSDATE program works with the following data types to display their internal values in a date or time format that you can understand:
- Date (old style)
- Date/Time (old style)
- Date/Time (TZ) (old style)
- Time (old style)
The following data types are stored in a date and time format that you can understand; therefore, you do not need to use the ARSDATE program to interpret the values:
- Date
- Date/Time
- Date/Time (TZ)
When displaying the date string for a given internal value, by default, the ARSDATE program displays the date string using the mm/dd/yy format. If you want the ARSDATE program to display the date string using a different format, then you must specify the date format with the -f parameter. For example:
```
     arsdate 10907

     10907 -> 11/11/99

     arsdate -f "%m/%d/%Y" 10907

     10907 -> 11/11/1999
```
When displaying the internal value for a given date string, by default, the ARSDATE program expects you to specify the date string using the mm/dd/yy format. If you want to specify the date string using a different format, then you must specify the date format with the -f parameter. For example:
```
     arsdate 11/12/99

     11/12/99 -> 10908

     arsdate 11/12/1999

     11/12/1999 -> -1 (Error)

     arsdate -f "%m/%d/%Y" 11/12/1999

     11/12/1999 -> 10908
```
