Question

I am trying to get the time of a timestamp but I keep getting the wrong time when I use Calendar.HOUR and Calendar.MINUTE,no matter what the timestamp is it tells me the hour is 10 and the minute is 12.

now when I use the Calendar.getTime() it gives me the correct time so I dont understand? I just want to get the hour in 12hr format and the minute

here is how i go about doing it

public static String getRealTime(long time){

            Calendar cal = Calendar.getInstance();
    Log.d("Calendar",String.valueOf(time));
    cal.setTimeInMillis(time);
    Date timeS = cal.getTime();
    String sTime = timeS.toString(); // gives correct time in 24hr format
    int hr = cal.HOUR;               // gives me 10 no matter what the timestamp is
    int min = cal.MINUTE;            // gives me 12 no matter what the timestamp is
    String dMin = getDoubleDigit(min);
    int ampm = cal.AM_PM;
    String m = new String();
    if(ampm == 0){
        m = "AM";
    }else{
        m="PM";
    }
    String rtime = String.valueOf(hr)+":"+dMin+" "+m;
    return rtime;
} 

so say the timestamp is 1316626200000 cal.getTime() gives me Wed Sep 21 13:30:00 EDT 2011 which would be the correct time but cal.HOUR gives me 10 for the hour which clearly is not what it should be. Why is it doing that?

Answer 1

cal.HOUR and cal.MINUTE are static final Integers for use in Calendar method calls. You would use this code to get the correct result:

   int hr = cal.get(Calendar.HOUR);
   int min = cal.get(Calendar.MINUTE);

Notice that I called the HOUR and MINUTE fields from Calendar and not your object cal. It is bad practice to call static members from an instantiated object.
