    //Get the milliseconds of the current time 
    int nowDateMilliseconds = DateUtil . getNowDateMs ( ) ; 
    print ( "nowDateMilliseconds: " + nowDateMilliseconds . toString ( ) ) ; 
    //I/flutter ( 7076): nowDateMilliseconds: 1562485927175
    
    //Get the current time 
    String nowDateStr = DateUtil . getNowDateStr ( ) ; 
    print ( "nowDateStr: " + nowDateStr . toString ( ) ) ; 
    //I/flutter ( 7076): nowDateStr: 2019-07-07 15:52:07
    
    //Get the week corresponding to the specified time 
    String zhWeekDayByMs = DateUtil . getZHWeekDayByMs ( 1562484092000 ) ; 
    print ( "zhWeekDayByMs: " + zhWeekDayByMs . toString ( ) ) ; 
    //I/flutter ( 7076): zhWeekDayByMs: Sunday
    
    //Convert date to milliseconds 
    int dateMsByTimeStr = DateUtil . getDateMsByTimeStr ( "2019-07-07 15:21:32" ) ; 
    print ( "dateMsByTimeStr: " + dateMsByTimeStr . toString ( ) ) ; 
    //I/flutter ( 7076) : dateMsByTimeStr: 1562484092000
    
    //Convert milliseconds to date format 
    String dateStrByMs = DateUtil . getDateStrByMs ( 1562484092000 ) ; 
    print ( "dateStrByMs: " + dateStrByMs . toString ( ) ) ;

    var format2 = TimelineUtil . format ( 1562484092000 ) ; 
    var format4 = TimelineUtil . format ( 1562466092000 ) ; 
    var format3 = TimelineUtil . format ( 1562311292000 )

    print("format "+format5);
