Java程序将Instant转换为LocalDateTime
假设您需要使用带有时区的IST将Instant转换为LocalDateTime：
创建即时消息：
Instant instant = new Date().toInstant();
现在，将Instant转换为LocalDateTime：
LocalDateTime date = LocalDateTime.ofInstant(instant, ZoneId.of(ZoneId.SHORT_IDS.get("IST")));示例
import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.util.Date;
public class Demo {
public static void main(String[] args) {
Instant instant = new Date().toInstant();
LocalDateTime date = LocalDateTime.ofInstant(instant, ZoneId.of(ZoneId.SHORT_IDS.get("IST")));
System.out.println("Date (IST) = " + date);
date = LocalDateTime.ofInstant(instant, ZoneId.of(ZoneId.SHORT_IDS.get("PST")));
System.out.println("Date (PST) = " + date);
date = LocalDateTime.ofInstant(instant, ZoneId.of(ZoneId.SHORT_IDS.get("EST")));
System.out.println("Date (EST) = " + date);
}
}输出结果
Date (IST) = 2019-04-18T13:32:26.923 Date (PST) = 2019-04-18T01:02:26.923 Date (EST) = 2019-04-18T03:02:26.923
