Android Question Dividing Time by 3

What is the meaning of dividing time? What is the expected result of 9:29 / 3 ?

I think he want to obtain something like
3:10
3:10
3:10 (about)
Intended as 3 minutes and 10 seconds, or hours and minutes.

convert to seconds (or minutes?):

9 * 60 + 29 = 569 seconds

divide by 3

569 / 3 = 189.667 seconds

convert back to mm:ss

round to nearest: Floor(189.667 + 0.5) = 190 seconds
or round down: Floor(189.667) = 189 seconds

Floor(189 / 60) = 3 minutes
189 - 3 * 60 = 9 seconds

03:09

same math works for hh:mm as well as for mm:ss
since there are both 60 minutes in hour and 60 seconds in minute

The important point here is not to use DateTime.Time or TimeParse. These methods are relevant when working with time instances, not durations.

B4X:

    Dim t As Long = ParseTimeDuration("09:29")
    t = t / 3
    Log(ConvertMillisecondsToString(t))

Private Sub ParseTimeDuration(HHMM As String) As Long
    Dim s() As String = Regex.Split(":", HHMM)
    Dim t As Long = s(0) * DateTime.TicksPerHour + s(1) * DateTime.TicksPerMinute
    If s.Length = 3 Then
        t = t + s(2) * DateTime.TicksPerSecond
    End If
    Return t
End Sub

Private Sub ConvertMillisecondsToString(t As Long) As String
    Dim hours, minutes, seconds As Int
    hours = t / DateTime.TicksPerHour
    minutes = (t Mod DateTime.TicksPerHour) / DateTime.TicksPerMinute
    seconds = (t Mod DateTime.TicksPerMinute) / DateTime.TicksPerSecond
    Return $"$2.0{hours}:$2.0{minutes}:$2.0{seconds}"$
End Sub
