java在JSP中获取两次时间差
在我的编码中，我使用jQuery日期选择器，在文本框中手动从用户那里获取时间[08][15][AM]3个不同的textboxes
我的代码是基于一个web应用程序来寻找一个高效的工人
每个工人将进入工作，以及每天完成工作所需的时间， 我在时间计算上有点挣扎 比如说
documentation work 08:15 AM - 01:15 PM = 5 hrs on the same day and
UI design 11:00 PM - 02:00 AM = 3 hrs on the next early morning
这些值写在textboxes中，而提交这些值将被带到servlet，在那里我想计算两个数字之间的差值，所以任何一个都请帮助我
我花了一个多星期的时间计算时差

请把日期也记下来。 您可以使用calendar对象并获得mill second。由此可以计算出时间差
