package com.testoutputtime;

import java.util.Calendar;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class TestoutputtimeActivity extends Activity {
	
	String TAG = "the time";
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        Calendar rightNow = Calendar.getInstance();
        
        int year = rightNow.get(Calendar.YEAR);
        int mounth = rightNow.get(Calendar.MONTH);
        int day = rightNow.get(Calendar.DAY_OF_MONTH);
        int hour = rightNow.get(Calendar.HOUR_OF_DAY);
        int minute = rightNow.get(Calendar.MINUTE);
        int second = rightNow.get(Calendar.SECOND);
        
        Log.e("TAG",String.valueOf(year)+ "," + String.valueOf(mounth)+ "," + String.valueOf(day)+ "," +String.valueOf(hour)+ "," + String.valueOf(minute)+ "," +String.valueOf(second));
        
     
        
    }
