Question

我需要为公司办公室制定一个倒数计时器小时：

一个办事处在巴西，另一个办事处在日本

巴西= UTC-03：00 JAPAN = UTC + 09:00

两个办事处都在上午8点营业，晚上8点关闭，当巴西办事处开业时，日本办事处正在关闭。

我如何配置日语，看到巴西办公室关闭，日本办公室开放，反之亦然

我的javascript代码：

function getTimeRemaining(endtime){

  var t = Date.parse(endtime) - Date.parse(new Date());
  var seconds = Math.floor( (t/1000) % 60 );
  var minutes = Math.floor( (t/1000/60) % 60 );
  var hours = Math.floor( (t/(1000*60*60)) % 24 );
  var days = Math.floor( t/(1000*60*60*24) );
  return {
    'total': t,
    'days': days,
    'hours': hours,
    'minutes': minutes,
    'seconds': seconds
  };
}


function initializeClock(endtime, clock_location, status, add_class, remove_class){

  clock_location.find('.relogio_status').removeClass(remove_class);
  clock_location.find('.relogio_status').addClass(add_class);

  var timeinterval = setInterval(function(){
    var t = getTimeRemaining(endtime);

    var show_message = ' '+status+' in ';

    if (t.days > 0) {
        show_message += t.days+" d ";
    }

    show_message += (t.hours < 10 ? '0':'')+t.hours+":"+(t.minutes < 10 ? '0':'')+t.minutes+":"+(t.seconds < 10 ? '0':'')+t.seconds;

    clock_location.find('.status_clock_text').html(show_message);

    if(t.total==0){
      // clearInterval(timeinterval);
      // location.reload();
      clock_city('rio_de_janeiro');
    }
  },1000);
}


function when_monday(){

Answer 1

部分问题是您的网站说巴西办公时间是08:00到20:00，日本办公时间是08:00到20:00。这些范围都不正确。巴西办公时间为11:00至23:00，日本办公时间为23:00至11:00。作为一般规则，除最终显示外，使用UTC。

rolling以UTC格式生成一个包含当前日期的Date对象。由于您的参考时间也是UTC，因此无需转换即可查找剩余时间。由于您实际上并不关心日期，只关注持续时间，因此您不需要对输出进行任何时区调整。

Answer 2

UTC偏移量可以添加到当前的UTC日期和时间：

＆＃13;

console.log( 'Z+0:',           new Date            )  // current UTC time
console.log( 'Z-3:', new Date( new Date -3 * 36e5) )  // current UTC time minus 3 hours
console.log( 'Z+8:', new Date(+new Date +8 * 36e5) )  // + used to convert to number

console.log( 'Tests:' )
console.log( 'Z+0:',           new Date(0)            )  // "1970-01-01T00:00:00.000Z"
console.log( 'Z-3:', new Date( new Date(0) -3 * 36e5) )  // "1969-12-31T21:00:00.000Z"
console.log( 'Z+8:', new Date(+new Date(0) +8 * 36e5) )  // "1970-01-01T08:00:00.000Z"
