> When running tests using the ExcelReader and inferring the schema, even
> though the date pattern 'M/d/yy' was specified (which per this
> [post|https://stackoverflow.com/questions/27571377/datetimeformatter-support-for-single-digit-day-of-month-and-month-of-year]
> should allow single digit months), dates like '1/1/18' are not inferred to
> be DATE:M/d/yy but rather STRING. The source for this is
> org.apache.nifi.util.text.RegexDateTimeMatcher whose regular expression for
> months requires two digits. It should be relaxed to allow for one or two
> digits.
