計(jì)算機(jī)二級(jí)VB輔導(dǎo):計(jì)算兩段時(shí)間的時(shí)間差

在寫程序時(shí),很多時(shí)候都要用到兩個(gè)給定時(shí)間的時(shí)間差,所以特地把這個(gè)函數(shù)寫出來(lái)以便以后可以方便的調(diào)用:
    function GetDoTime(Time1, Time2)
    Dim stime
    If Time1 > Time2 Then
    stime = Time1
    Time1 = Time2
    Time2 = stime
    End If
    secondvalue = DateDiff("s", Time1, Time2)
    dayvalue = DateDiff("d", Time1, Time2)
    hourvalue = Fix((secondvalue - dayvalue * 24 * 3600) / 3600)
    If hourvalue < 0 Then dayvalue = dayvalue - 1: hourvalue = 24 + hourvalue
    minitevalue = Fix((secondvalue - dayvalue * 24 * 3600 - hourvalue * 3600) / 60)
    If minitevalue < 0 Then hourvalue = hourvalue - 1: minitevalue = 60 + minitevalue
    secvalue = secondvalue - dayvalue * 24 * 3600 - hourvalue * 3600 - minitevalue * 60
    If secvalue < 0 Then minitevalue = minitevalue - 1: secvalue = 60 + secvalue
    GetDoTime=dayvalue & "天" & hourvalue & "小時(shí)" & minitevalue & "分" & secvalue & "秒"
    End function
