[android help] TimePicker Saves Zero Value in Android SQLite Database

I have a TimePicker which I'd like to use to determine a length of time a user can stay connected. Lets say the time now is 10:00 if the user selects 11:00 - I'd like the source code below to determine that there are 60 minutes between the current time - and the time selected and set that to a string/long (minutes) which I then have displayed as a textview.

I've coded everything as I thought it should be - however the textview never seems to update with the time selected. Everytime I attempt to view the data - I get a value of 0 not matter what the timepicker is set to.

Anyone have any suggestions? I'm stumped at the moment and I'm not sure what else to try.

ADDEDITDEVICE.JAVA (where the timepicker and minutes determination takes place)

public class AddEditDevice extends Activity {

     private long rowID; 
     private EditText nameEt;
     private EditText capEt;
     private EditText codeEt;
     private TimePicker timeEt;
     private TextView ssidTextView;
     Date date = new Date();
     TimePicker tp;




      // @Override
       public void onCreate(Bundle savedInstanceState) 
       {
          super.onCreate(savedInstanceState); 
          setContentView(R.layout.add_country);
          WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
          WifiInfo info = wifi.getConnectionInfo();
          String ssidString = info.getSSID();

          if (ssidString.startsWith("\"") && ssidString.endsWith("\"")){
              ssidString = ssidString.substring(1, ssidString.length()-1);


          //TextView ssidTextView = (TextView) findViewById(R.id.wifiSSID);
          ssidTextView = (TextView) findViewById(R.id.wifiSSID);
          ssidTextView.setText(ssidString); 

          nameEt = (EditText) findViewById(R.id.nameEdit);
          capEt = (EditText) findViewById(R.id.capEdit);
          codeEt = (EditText) findViewById(R.id.codeEdit);
          timeEt = (TimePicker) findViewById(R.id.timeEdit);






          Bundle extras = getIntent().getExtras(); 

          if (extras != null)
          {
             rowID = extras.getLong("row_id");
             nameEt.setText(extras.getString("name"));  
             capEt.setText(extras.getString("cap"));  
             codeEt.setText(extras.getString("code"));    
             String time = extras.getString("time");
             String[] parts = time.split(":");
             timeEt.setCurrentHour(Integer.valueOf(parts[0]));
             timeEt.setCurrentMinute(Integer.valueOf(parts[1]));
             timeEt.setIs24HourView(false);
