可以使用下面的代码：

[code]long diff = d2.getTime() - d1.getTime();//as given

long seconds = TimeUnit.MILLISECONDS.toSeconds(diff);  
long minutes = TimeUnit.MILLISECONDS.toMinutes(diff); [/code]

如果计算不同的天数：

[code]long diff = d2.getTime() - d1.getTime();//as given

long days= TimeUnit.MILLISECONDS.toDays(diff); [/code]
