Option Explicit

Private Sub Timer1_Timer()

    UpLbl.Caption = FormatCount(GetTickCount, DaysHoursMinutesSecondsMilliseconds)

End Sub


Public Enum TimeFormatType

    DaysHoursMinutesSecondsMilliseconds = 0

    DaysHoursMinutesSeconds = 1

Public Function FormatCount(Count As Long, Optional FormatType As TimeFormatType = 0) As String

    Dim Days As Long, Hours As Long, Minutes As Long, Seconds As Long


    Count = Count \ 1000

    Days = Count \ (24& * 3600&)

    If Days > 0 Then Count = Count - (24& * 3600& * Days)

        Hours = Count \ 3600&

    If Hours > 0 Then Count = Count - (3600& * Hours)

    Minutes = Count \ 60

    Seconds = Count Mod 60

I believe that there is an issue if you have more than 25 days. You can store the from date and time in a variable and the finaldate and time in another variable and then find the up time.
