计算时间和日期差异(Calculating Time and Date difference)

 我目前正在编写一份报告来计算iReport中两个日期变量之间的TotalTimeDifference 。  
 我正在比较的两个变量是MO_DATECREATED和MO_DATECOMPLETED并且我试图只计算时间差。  
 我曾尝试设置一个变量，对两个变量进行简单的减法 - 当然，这根本没有奏效。  
 我会附上我目前拥有的照片，但我正在寻找比较两个变量（包含日期/时间）和打印出时间差异变量的方式。  
 例如：如果MO started at 1/2/15 12:55pm并completed at 1/3/15 1:55pm我想打印时间差或花费多少时间为25 hours  
 我如何在iReport中做到这一点？ 感谢您帮助新手！  
 
 编辑答案后，我想展示的日子： 

I am currently writing a report to calculate the TotalTimeDifference between two date variables in iReport.  
The two variables that I am comparing are MO_DATECREATED and MO_DATECOMPLETED and I am trying to calculate the time difference only. 
I have tried setting up a variable that does a simple subtraction of the two variables- and of course that has not worked at all. 
I will attach photoes of what I currently have but I am looking for the way to compare the two variables (which contains date/time) and printing out a variables with the difference in time. 
Example: If the MO was started at 1/2/15 12:55pm and completed at 1/3/15 1:55pm i want to print the time difference, or how long it took, as 25 hours 
How can I do this in iReport? Thank you for helping out a newbie! 
  
EDIT After answer, I would like to the show days to:

 你可以这样做：  
$(".user").click(function () {
    // Hide it but only if not hidden - hide
    $('.trigger:visible').hide();

    // Later in the script - Show it but only If it's not visible.  
    $('.trigger:hidden').show();
});
 
 对于更多的上下文，在下列情况下元素被视为“隐藏”：  
 
  它们的CSS显示值为none。  
  它们是type =“hidden”的表单元素。  
  它们的宽度和高度显式设置为0。  
  或者祖先元素被隐藏，所以元素不会显示在页面上。  
 
 此外，“具有可见性的元素：隐藏或不透明度：0被认为是可见的。”

You can do this: 
$(".user").click(function () {
    // Hide it but only if not hidden - hide
    $('.trigger:visible').hide();

    // Later in the script - Show it but only If it's not visible.  
    $('.trigger:hidden').show();
});
 
For some more context, elements are deemed ":hidden" if: 
 
 They have a CSS display value of none. 
 They are form elements with type="hidden". 
 Their width and height are explicitly set to 0. 
 Or an ancestor element is hidden, so the element is not shown on the page. 
 
Additionally, "elements with visibility: hidden or opacity: 0 are considered to be visible."
