It looks like the dateTransforms may not be handling null or undefined input as expected.
Given the following test-case:
expect(mapperUtils.dateTransformer(null)).to.be.undefined;
The dateTransformer returns '1970-01-01'.
Would it be reasonable to expect these transformers to return undefined in the event the input data is not truthy and/or possibly when the string is not a valid format -- moment(date_string).isValid === false?
