You can implement it in your code instead:

B4X:

Sub AddMinutes(TimeString As String, add As Int) As String
   Dim i As Int = TimeString.IndexOf(":")
   Dim hours As Int = TimeString.SubString2(0, i)
   Dim minutes As Int = TimeString.SubString(i + 1)
   minutes = minutes + add
   hours = hours + minutes / 60
   minutes = minutes Mod 60
   Return NumberFormat(hours, 2, 0) & ":" & NumberFormat(minutes, 2, 0)
End Sub

(haven't tested the code...)

Thanks Erel,above code is working, Now I have solved my problem.Can u give me example code for Subtracting minutes..such as (06:01) should become (05:58).Eagerly waiting for your prompt reply.

Change these two lines:

B4X:

hours = hours + minutes / 60
 minutes = minutes Mod60

To:

B4X:

hours = hours + Floor(minutes / 60)
 minutes = (minutes + 60) Mod 60

It should now work with positive and negative values.
