What file type did you get that value from?
IF this is direct transfer from some other data system then that data likely uses a different base day number to date than SAS uses (01JAN1960).
Since you do not have a 24 in that random number then it appears that none of the digits correspond to day of month, month and the 22 may just be coincidence as a possible year value. (2-digit years are bad idea in general).
