Is it possible to store a timestamp on a SAS Dataset date column that will contain milliseconds as well?
You first have to convert a date column (days from 01jan1960) to a datetime column (seconds from 01jan1960:00:00:00), then you can use the fractional part of the datetime value to store fractions of a second. Use datetime23.3 as format to display milliseconds.
No. Date type variable (integer) is different with DateTime(double) type variable. You should firstly know what kind of variable you should use .

I just want to make sure about the following:
data timestamp;
date1 = date();
date2 = datetime();
run;
date1 contains the number of days from 1 JAN 1960 and date2 contains the number of seconds from midnight 1 JAN 1960.
How do I create a variable date3 that contains the number of milliseconds from 1 JAN 1960?
If you only want to display the total number of milliseconds, just multiply the datetime value by 1000. And use a simple numerical format instead of a datetime format.

Thanks KurtBremser,
It looks like it is working when I create two data steps in order to "delay" execution I can see that the timestamp per millisecond is different.
data time1;
date1 = datetime();
run;
data time2;
date1 = datetime();
run;
data time;
set time1 time2;
format date: datetime23.3;
run;
proc print;
run;
