Enum을 이용한 Date 포맷

import java.time.LocalDate;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
import java.util.Date;

/**
 * This pattern has the following benefits:
 *
 *  - Date formats are referenced as a strong type
 *  - Code completion on patterns
 *  - Patterns can be javadoc'ed
