Problem Note 35412: ANYDTDTM informat reads datetime values as dates
When reading datetime values with PROC IMPORT or the Import Wizard, often the ANYDTDTM informat is used since it can read many different styles of datetime values. When a value that is ambiguous is read, SAS may read the datetime value as a date only. This results in different results than the coder anticipated.
A sample value is 1/1/09 1:15. The three values could be month, day, or year values on a calendar. When this occurs, the DATESTYLE= system option value is used to determine which order to assume the month, day, and year values to be ordered.
A workaround for this type of value is to specify the MDYAMPM informat for reading the above value.
The following code also reproduces a known issue where ANYDTDTM informat doesn't know how to read the given value. Instead of returning a missing value, a crash can occur.
data _null_;
x=input("31000.55SHP002",anydtdtm14.);
put x=;
run;
