I have a database that time stamps every five minutes, or less if the user stops the database. How can I take the sum of the difference between the time stamps and add them up?

我有六次不同的时间,每五分钟五分五分钟,而一次,只有两分钟时间,而最后的汽车时间被用户拖了:
13:41:33
13:46:33
1351:33
13:56:33
14:01:33
14:06:33
14:08:27
我现在要谈谈过去历时多分钟的一点:
13:41:33 = 0 / / 将成为零原因,即用户开始时间
13:46:33 = 5
1351:33 = 5
页: 1
14:01.33 = 5
14:06.33 = 5
页: 1
之后,我请求听取所有五位和两党的意见,并补充:
0+
5 +
5 +
5 +
5 +
5 +
2 =
27分钟
