js 获取俩时间段

const now = new Date();
console.log(now); // 输出当前日期和时间

// 获取开始时间
const startDate = new Date();
startDate.setHours(9, 0, 0, 0); // 设置为当天的 9:00:00

// 获取结束时间
const endDate = new Date();
endDate.setHours(18, 0, 0, 0); // 设置为当天的 18:00:00

console.log("开始时间:", startDate);
console.log("结束时间:", endDate);

function getTimeDifference(startDate, endDate) {
    const startTimestamp = startDate.getTime();
    const endTimestamp = endDate.getTime();
    const differenceInMilliseconds = endTimestamp - startTimestamp;
    const differenceInSeconds = differenceInMilliseconds / 1000;
    const differenceInMinutes = differenceInSeconds / 60;
    const differenceInHours = differenceInMinutes / 60;

    return {
        milliseconds: differenceInMilliseconds,
        seconds: differenceInSeconds,
        minutes: differenceInMinutes,
        hours: differenceInHours
    };
}

const timeDifference = getTimeDifference(startDate, endDate);
console.log("时间差:", timeDifference);

const formattedDate = now.toLocaleString();
console.log("格式化后的日期:", formattedDate);
