    Code:
    Sub SetDateTime(ToDate As String, ToTime As String)
        
    'date needs to be in yyyymmdd format
        'time needs to be in hhmmss 24-hour
        'date -s 20120419.024012; \n
       
        
    Dim Command, Runner As String
        
    Dim StdOut, StdErr As StringBuilder
        
    Dim Result As Int
        
    Dim Ph As Phone
       
        StdOut.Initialize
        StdErr.Initialize

        Runner = 
    File.Combine(File.DirInternalCache, "runner")
        Command = 
    File.Combine(File.DirInternalCache, "command")
        
    File.WriteString(File.DirInternalCache, "runner""su < " & Command)
        
    File.WriteString(File.DirInternalCache, "command""date -s " & ToDate & "." & ToTime & "; \n" & CRLF & "exit")
        Result = Ph.Shell(
    "sh"Array As String(Runner), StdOut, StdErr)
    End Sub

    That code doesn't really work, some devices do not have "su".

    If you have a rooted device, then you probably already have super user installed or can easily install it.

    Thanks. It works fine, but one comment about date format. It should be in "yyyyMMdd" format (i.e. MM for month not mm!)
