将时长与时间差一起使用

你还可以使用 dayjs#diff 的持续时间来获取两个日期时间之间的持续时间。为此，只需将 dayjs#diff 方法传递给 dayjs#duration，如下所示：

¥You can also use duration with dayjs#diff to get the duration between two date times. To do so, simply pass the dayjs#diff method into dayjs#duration as follows:

var x = dayjs()
var y = dayjs()

var duration = dayjs.duration(x.diff(y))
// returns duration object with the duration between x and y
