Java Data Type - 如何得到抵消ZoneOffset日期时间

import java.time.LocalDateTime;
import java.time.Month;
import java.time.OffsetDateTime;
import java.time.ZoneOffset;

public class Main {
  public static void main(String[] args) {
    // using offsets
    LocalDateTime date = LocalDateTime.of(2013, Month.JULY, 20, 3, 30);
    ZoneOffset offset = ZoneOffset.of("+05:00");

    // 2013-07-20 22:30 +05:00
    OffsetDateTime plusFive = OffsetDateTime.of(date, offset);
    System.out.println(plusFive);

    // 2013-07-19 20:30 -02:00
    OffsetDateTime minusTwo = plusFive.withOffsetSameInstant(ZoneOffset.ofHours(-2));
    
    System.out.println(minusTwo);
  }
}
