Question

我有一个XML文件，其中包含一些带有起点和终点的日期，如下所示：

body, html {
  
  margin: 0;
  width: 100%;
  height: 100%;
 font-size: 16px;
  
}

* {
  
  box-sizing: border-box;
  
}

#wrap {
  
  background-color: red;
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  padding: 40px;
  flex-direction: column;
  
}

#box {
  
  background-color: #dcdcdc;
  padding: 10px;
  border-radius: 10px;
  display: flex;
  flex-direction: column;
  /*width: 100%; this works, but dont want it full until box is equal or smaller than content*/
  
  
}

#box > div {
  
  flex: 1 0 auto!important;
  
}

#title {
  
  text-align: center;
  margin-bottom: 20px;
  font-size: 20px;
  color: blue;
}

table {
  
  border-spacing: 0;
  border-collapse: collapse;
  table-layout: auto;
  white-space: nowrap;
  width: 100%;
}

table thead {
  
  font-weight: bold;
}

table tbody tr {
  
  height: 30px;
}

table td {
  
  padding: 0 5px;
}

#list {
  
  overflow: auto;
  background-color: rgba(0,0,0,0.05);
  
}

如何计算这两个日期之间的差（以毫秒（MS）为单位）？

我从michael.hor257k中找到了一些内容：Finding the difference between two dateTimes in XSLT 但不幸的是，我的水平太差了，无法重复使用此：（
