Need to convert a datetime number into Date format

[DarrylLawrence]

I have a Date column that has been formatted as a number and the datetime is reflected as a number, eg 1753920000

I need to convert this to a date format, eg 20151001 or 01OCT.

Thanks

data _NULL_;
 a='22JUN2019:23:14:12'dt;
 put a=;
 put a= datetime.;
 b=datepart(a);
 put b=;
 put b= date9.;
run;

I solved the problem as follows:

data VALID_DATE;
set source table;

valid_end_date_1=datepart(input(put(valid_end_dt1,datetime20.),datetime20.));

format valid_end_date_1 date5. ;
run;

Results:

VALID_END_DT1	VALID_END_DATE_1
1753920000	31-Jul
1753920000	31-Jul

Since valid_end_dt1 contains valid SAS datetime values (otherwise the datetime20. format would never work), you can apply the datepart function directly to it. No need for the double conversion.

So your code would be

data VALID_DATE;
set source table;
valid_end_date_1=datepart(valid_end_dt1);
format valid_end_date_1 date5.;
run;

Thanks Kurt, it works!

Rather than use datepart() function to convert the value, you could use the DTDATE. format to present just the date without any other conversion.
