简单的问题:从时间戳参数到日期

import datetime

# 假设我们有一个UNIX时间戳
timestamp = 1633072800

# 转换为本地时间
local_time = datetime.datetime.fromtimestamp(timestamp)
print("Local Time:", local_time)

# 转换为UTC时间
utc_time = datetime.datetime.utcfromtimestamp(timestamp)
print("UTC Time:", utc_time)

// 假设我们有一个UNIX时间戳（毫秒级）
let timestamp = 1633072800000;

// 转换为本地时间
let localTime = new Date(timestamp);
console.log("Local Time:", localTime);

// 转换为UTC时间
let utcTime = new Date(timestamp).toUTCString();
console.log("UTC Time:", utcTime);

import java.util.Date;
import java.text.SimpleDateFormat;

public class TimestampToDate {
    public static void main(String[] args) {
        // 假设我们有一个UNIX时间戳（秒级）
        long timestamp = 1633072800L;

        // 转换为本地时间
        Date localDate = new Date(timestamp * 1000);
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println("Local Time: " + sdf.format(localDate));

        // 转换为UTC时间
        sdf.setTimeZone(java.util.TimeZone.getTimeZone("UTC"));
        System.out.println("UTC Time: " + sdf.format(localDate));
    }
}
