Function TimeDiff(sBegin, sEnd)

Dim iHourB, iMinuteB, iSecondB, iMiniSecondB

Dim iHourE, iMinuteE, iSecondE, iMiniSecondE

Dim dTimeB, dTimeE, dTimeDiff

Dim iHour, iMinute, iSecond, iMiniSecond

iHourB = clng(Left(sBegin, 2))

iMinuteB = clng(Mid(sBegin, 4, 2))

iSecondB = clng(Mid(sBegin, 7, 2))

iMiniSecondB = clng(Mid(sBegin, 10, 4))

iHourE = clng(Left(sEnd, 2))

iMinuteE = clng(Mid(sEnd, 4, 2))

iSecondE = clng(Mid(sEnd, 7, 2))

iMiniSecondE = clng(Mid(sEnd, 10, 4))

dTimeB = iHourB * 3600 + iMinuteB * 60 + iSecondB + iMiniSecondB / 1000

dTimeE = iHourE * 3600 + iMinuteE * 60 + iSecondE + iMiniSecondE / 1000

dTimeDiff = dTimeE - dTimeB

iHour = Int(dTimeDiff / 3600)

dTimeDiff = dTimeDiff - iHour * 3600

iMinute = Int(dTimeDiff / 60)

dTimeDiff = dTimeDiff - iMinute * 60

iSecond = Int(dTimeDiff)

dTimeDiff = dTimeDiff - Int(dTimeDiff)

iMiniSecond = dTimeDiff

TimeDiff = iHour & "小时" & iMinute & "分钟" & iSecond & FormatNumber(iMiniSecond, 3) & "秒"
