自定义时差函数(加入跨天计算功能)

通过datediff()函数综合运用,加入跨天计算时差,得出精确到分钟的时间差

Public Function TimeDiff(StarD As Date, EndD As Date, StarT As Date, EndT As Date) As String

    Dim myDateDiff As Date
    Dim myMinuteDiff As Date


    myDateDiff = Datediff("d", StarD, EndD)
    myMinuteDiff = Datediff("n", StarT, EndT)

    ''判断日期是否超过一天

    If myDateDiff > 0 Then
        myMinuteDiff = Datediff("n", StarT, EndT) + myDateDiff * 24 * 60
    Else
        myMinuteDiff = Datediff("n", StarT, EndT)
    End If

    TimeDiff = Format(Int(myMinuteDiff / 60), "00") & ":" & Format(myMinuteDiff Mod 60, "00")
End Function
