		String validPatterns5 = "yyyy-MM-dd HH:mm:ss";
		
		System.out.println("SimpleDateFormat in UTC format with different pattern: \n");
		
		SimpleDateFormat simpleDateFormat = new SimpleDateFormat(validPatterns1);
		simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));		
		System.out.println("EEE, MMM d, ''yy:--> "+simpleDateFormat.format(new Date()));
		
		simpleDateFormat = new SimpleDateFormat(validPatterns2);
		simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
		System.out.println("h:mm a:--> "+simpleDateFormat.format(new Date()));
		
		simpleDateFormat = new SimpleDateFormat(validPatterns3);
		simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
		System.out.println("YYYY-'W'ww-u:--> "+simpleDateFormat.format(new Date()));
		
		simpleDateFormat = new SimpleDateFormat(validPatterns4);
		simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
		System.out.println("yyyy-MM-dd:--> "+simpleDateFormat.format(new Date()));
		
		simpleDateFormat = new SimpleDateFormat(validPatterns5);
		simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
		System.out.println("yyyy-MM-dd HH:mm:ss:--> "+simpleDateFormat.format(new Date()));
