		String date = new SimpleDateFormat("yyyyMMddHHmmss")
				.format(calendar.getTime());
		System.out.println("date" + date);

Where are you?  I am in California.  Try using  
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("America/Los_Angeles"));

Hi him121,

Please try one of this will solve your problem.

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
System.out.println(dateFormat.format(date));

or

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar cal = Calendar.getInstance();
System.out.println(dateFormat.format(cal.getTime()));

Thanks & Regards,

Hi him21,

prefer using the Calendar object like below.

Calendar now = GregorianCalendar.getInstance()
You can also get a Date object from the Calendar. More reference below link.

Same Result,all these code i have tried before also:)

            String patternString = "yyyyMMddhhmmss";
            DateFormat utcFormat = new SimpleDateFormat(patternString);
            utcFormat.setTimeZone(TimeZone.getTimeZone("Asia/Kolkata"));
               
      System.out.println(+utcFormat.getTimeZone() +"::"+utcFormat.format(new Date()));

output ->

sun.util.calendar.ZoneInfo[id="GMT",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]::20140320030003
