我应该如何获得某些特定格式的时间，比如我想得到时间hh：mm am / pm然后添加一些分钟。
例如，我的日期2016-09-16T11:40:50.000Z首先得到时间11:40 am，然后再添加20分钟，得到12:00 am之类的结果
那么，我该怎么做呢。
我尝试date.getTime（），但它没有给我我想要的适当时间。

function gettime(date) {
var hours = date.getHours();
var minutes = date.getMinutes();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0'+minutes : minutes;
return = hours + ':' + minutes + ' ' + ampm;
}

for adding more minutes you can use
date.getMinutes() + 20; //It will add 20 minutes
