calculate total hours and minutes between two times but .....

I use this code...
Timediff = Format(CDate(TimeNow) - CDate(TimeFirst), "Long Time")

but if i change windows clock to the next day, for example:

now = 25-nov-2004 11:07:15
first = 24-nov-2004 11:00:00

i want to get this timediff:

24:07:15


no ....
0:07:15

can you help me?

I use this function when calculating such things...

[code]
Public Function TimeDiff(LesserTime As String, LesserTimeDate As String, GreaterTime As String, GreaterTimeDate As String) As String
Dim Thrs As Single, Tmins As Single, Tsecs As Single, ReturnTime As String
Dim DTcheck As Single
Dim i, Var_tmp_Hour As Integer

DTcheck = DateDiff("d", LesserTimeDate, GreaterTimeDate)

Var_tmp_Hour = Hour(GreaterTime)
If DTcheck > 0 Then
  For i = 1 To DTcheck
    Var_tmp_Hour = Var_tmp_Hour + 24
  Next
 
 ElseIf DTcheck < 0 Then
  TimeDiff = "ERROR"
  Exit Function
End If
Thrs = Var_tmp_Hour - Hour(LesserTime)


If Thrs > 0 Then
  Tmins = Minute(GreaterTime) - Minute(LesserTime)
  If Tmins < 0 Then
    Tmins = Tmins + 60
    Thrs = Thrs - 1
  End If
 ElseIf Thrs = 0 And Minute(GreaterTime) > Minute(LesserTime) Then
   Tmins = Minute(GreaterTime) - Minute(LesserTime)
  Else
   TimeDiff = "ERROR"
   Exit Function
End If
Tsecs = Second(GreaterTime) - Second(LesserTime)
If Tsecs < 0 Then
  Tsecs = Tsecs + 60
  If Tmins > 0 Then Tmins = Tmins - 1 Else Tmins = 59
End If
TimeDiff = Thrs & ":" & Tmins & ":" & Tsecs
End Function
[/code]

To use it just call something like this:

[code]
MsgBox TimeDiff("11:00:00", "24/11/2004", "11:07:15", "25/11/2004")
[/code]

Try using DateDiff ...

DateDiff("n",#24/11/2004 23.30#,#25/11/2004 23.35#)/60.0
