    You'll want to convert your date to a polynominal type first instead of a numerical (since numericals will be converted based on the number of milliseconds from midnight on Jan 1, 1970, which is why you have the dates that you do). In your example, after converting to a nominal (use Numerical to Nominal), the correct pattern for the Nominal to Date operator would be  yyyyMMdd
