我必須點(diǎn)擊一個(gè)我無法修復(fù)的API，我需要啟動一個(gè)計(jì)時(shí)器以顯示某人排隊(duì)的時(shí)間。我回來的日期是這種格式1556214336.316。問題是年份始終顯示為1970，但是時(shí)間是正確的開始時(shí)間。我需要計(jì)算現(xiàn)在的時(shí)間與創(chuàng)建對話的時(shí)間之間的差。我嘗試了這一點(diǎn)，但收效甚微，我想知道是否有一種優(yōu)雅的方法來僅獲取時(shí)間差而不是總秒數(shù)。 convertDateToTimerFormat = (time) => {    const now = new Date();    const diff = Math.round((now - parseInt(time.toString().replace('.', ''))) / 1000);    const hours = new Date(diff).getHours();    const minutes = new Date(diff).getMinutes();    const seconds = new Date(diff).getSeconds();    return `${hours}:${minutes}:${seconds}`;}怪異的parseInt(time.toString().replace('.', '')))似乎解決了1970年的問題，但是我仍然無法獲得所需的數(shù)據(jù)。我嘗試了momentjs庫，但是他們的diff方法似乎只允許幾天和幾個(gè)小時(shí)。任何幫助/指導(dǎo)，將不勝感激。使用工作代碼進(jìn)行編輯：  convertDateToTimerFormat = (time) => {    const now = new Date();    // eslint-disable-next-line radix    const diff = new Date(Number(now - parseInt(time.toString().replace(/\./g, ''))));    const hours = diff.getHours();    const minutes = diff.getMinutes();    const seconds = diff.getSeconds();    return `${hours}:${minutes}:${seconds}`;  }
