几年前，我写了一个“通用的”日期函数:

function addToDate({time_unit, operator, offset_value }) {
        const date = new Date();
  operator = operator == "after" ? "+" : "-";
  switch (time_unit) {
    case "seconds":
        date.setSeconds(eval(`${date.getSeconds()} ${operator} ${offset_value}`));
    break;

    case "hours":
        date.setHours(eval(`${date.getHours()} ${operator} ${offset_value}`));
      break;

    case "minutes":
        date.setMinutes(eval(`${date.getMinutes()} ${operator} ${offset_value}`));

      break;
    case "days":
        date.setDate(eval(`${date.getDate()} ${operator} ${offset_value}`));
      break;

    case "months":
        date.setMonth(eval(`${date.getMonth()} ${operator} ${offset_value}`));

      break;
    case "years":
        date.setFullYear(eval(`${date.getFullYear()} ${operator} ${offset_value}`));
      break;
    default:
      break;
  }

  return date;
}

const new_date = addToDate({time_unit:'seconds','operator':'after','offset_value':10});

console.log(new_date.toISOString());

如果你需要在当前时间上增加10秒，你可以使用:

const date = new Date();
date.setUTCSeconds(date.getUTCSeconds() + 10); // Change 10 to any number of seconds

timeObject.setSeconds(timeObject.getSeconds() + 10)

你可以使用setSeconds方法获取今天的秒数，并在其中添加10秒 var today = new Date(); today.setSeconds(today.getSeconds() + 10); 您可以添加10 *1000毫秒的新日期: var today = new Date(); today = new Date(today. gettime () + 1000*10); 你可以使用setTime: settime (now.getTime() + 10000)

// let timeObject = new Date();
// let milliseconds= 10 * 1000; // 10 seconds = 10000 milliseconds
timeObject = new Date(timeObject.getTime() + milliseconds);

在node.js下，.setSeconds为我揭示了非常奇怪的错误行为，所以我使用:

dateAddSeconds(date, seconds){ 
    return new Date( Date.parse(date) + seconds*1000 );
}
