Visual Basic - Alguien me puede ayudar con este contador de horas

'Nota:como puedo hacer que este contador me calcule el valor del tiempo en un texbox en 'dinero

Option Explicit
Private Time As Double
Dim cal As Double
Dim timemin As Double

Private Function CalculateTime(Time As Double) As String
Dim TimeHour As Double
Dim strTimeHour As String
Dim timemin As Double
Dim strTimeMin As String
Dim TimeSec As Byte
Dim strTimeSec As String

'Calculate the actual times
TimeHour = Int((Time / 60) / 60)
timemin = Int(Time / 60)
timemin = timemin Mod 60
TimeSec = Int(Time Mod 60)

'Change times to appropriate formats
strTimeMin = timemin
If Len(strTimeMin) = 1 Then
strTimeMin = "0" & strTimeMin
End If

strTimeSec = TimeSec
If Len(strTimeSec) = 1 Then
strTimeSec = "0" & strTimeSec
End If

strTimeHour = TimeHour
If Len(strTimeHour) = 1 Then
strTimeHour = "0" & strTimeHour
End If

'Assign the appropriate values to the label
CalculateTime = strTimeHour & ":" & strTimeMin & ":" & strTimeSec

End Function

Cual seria el uso ? parece un tarifador de un cyber , suponele que cobras $ 1 los 15 min , y vos pones a correr un timer que te 2 horas los convertis a min y con regla de 3 sacarias cuanto pagaria
Vi muy por encima tu codigo , pero ...

Dim TimeHour As Double
TimeHour = Int((Time / 60) / 60)

declaras una cosa y asignas otra ? si mal no recuerdo INT toma la parte entera , entoces para que double , no?
