Subtract time from time

Hi,

I have a total mental block today and need help with this "simplistic" problem...

I have a counter ie "01:00:00". I need to subtract say "00:54:32" from it, giving me the total counter (time) remaining in hh:mm:ss format.

The counter is NOT AM/PM dependant, so using TimeSerial, or TimeValue does not work. Can someone help me out please?

Many thanks.

Kind regards,

Hi !

I assume the two source were string cuz you didn't stated cleary what are the type of input and the types of output expected. My proposed answer were :

Private Sub Command1_Click()
    Dim a1 As String
    Dim a2 As String
   
    a1 = "01:00:00"
    a2 = "00:54:32"
    MsgBox Format(CDate(a1) - CDate(a2), "hh:mm:ss")
End Sub
The message pops "00:05:28".
