Subtract from another date object
从另一个日期对象中减去
var d = new Date();
d.setHours(d.getHours() - 2);

According to Javascript Date Documentation, you can easily do this way:
根据Javascript Date Documentation，您可以轻松地这样做：
var twoHoursBefore = new Date();
twoHoursBefore.setHours(twoHoursBefore.getHours() - 2);
And don't worry about if hours you set will be out of 0..23range.
Date() object will update the date accordingly.
不要担心您设置的小时数是否超出0..23范围。Date() 对象将相应地更新日期。
