问题描述
我正在开发一个计算时间差的系统.如何比较两个时间(带日期)并获得小时数和时间?分钟的差异?
I'm developing a system to calculate time difference. How can I compare two time (with date) and get the hours & minutes of the difference?
示例1:
datetime1 = 1-Apr-2014 01:05:04 AM
datetime2 = 1-Apr-2014 02:05:04 AM
结果将是:
datetime2 - datetime1 = 01 Hours 00 Minutes
示例2:
datetime1 = 1-Apr-2014 01:05:04 AM
datetime2 = 2-Apr-2014 02:15:04 AM
结果将是:
datetime2 - datetime1 = 25 Hours 10 Minutes
一个负值(对于datetime1> datetime2)也将有助于指示datetime1大于datetime2
A negative value (for datetime1 > datetime2) would also be helpful for indicating that datetime1 is greater than datetime2
示例:
datetime1 = 2-Apr-2014 01:05:04 AM
datetime2 = 1-Apr-2014 01:05:04 AM
结果将是:
datetime2 - datetime1 = -24 Hours 00 Minutes
谢谢！
推荐答案
我的建议是使用类似的东西
My recommendation would be to use something like
Dim minutesDiff = DateDiff(DateInterval.Minute,datetime1,datetime2)
Console.WriteLine("{0} hours {1} minutes", Math.Abs(minutesDiff) / 60, Math.Abs(minutesDiff) Mod 60)
要将其扩展到秒:
Dim secondsDiff = DateDiff(DateInterval.Second,datetime1,datetime2)
Console.WriteLine("{0} hours {1} minutes {2} seconds", Math.Abs(secondsDiff)/3600, (Math.Abs(secondsDiff) Mod 3600) / 60, Math.Abs(secondsDiff) Mod 60)
