Date d = new Date( System.currentTimeMillis() ); lblDate = new LabelField(d.toString()); this will return Long Date Including timizone and all the things. but if you want a format the date time to shor, long or medium you can use following method. Medium Date SimpleDateFormat df = new SimpleDateFormat(SimpleDateFormat.DATE_MEDIUM);     String Mydate = df.format(new Date(System.currentTimeMillis())); Ex:- Mar 08, 2006. Short Date SimpleDateFormat df = new SimpleDateFormat(SimpleDateFormat.DATE_SHORT);  String Mydate = df.format(new Date(System.currentTimeMillis())); Ex:- 03.08.06. Long Date SimpleDateFormat df = new SimpleDateFormat(SimpleDateFormat.DATE_LONG);  String Mydate = df.format(new Date(System.currentTimeMillis())); Ex:- Wednesday, March 08, 2006. Custom Date SimpleDateFormat df = new SimpleDateFormat( "MMMM, dd yyyy" );  String Mydate = df.format(new Date(System.currentTimeMillis())); Ex:- March 08, 2006. Some Formating Examples "yyyy.MM.dd G 'at...

I used folloeing coding to set main screen backgroung color with out the scoll bar in component pack 4.5. public class frmLogin extends MainScreen { VerticalFieldManager vmain; public frmLogin()  {        super( NO_VERTICAL_SCROLL );       vmain = new VerticalFieldManager( USE_ALL_HEIGHT |USE_ALL_WIDTH )      {  protected void paint(net.rim.device.api.ui.Graphics graphics)          {      graphics.setBackgroundColor(0xe6e7e8);  // 0xRRGGBB or Color.Blue          graphics.clear();  super.paint(graphics);         }       };            // Add other controlers to vmain            add(vmain); }
