我的輸入字符串:
11/28/2012 8:59am
我的代碼:
String dtStart = "11/28/2012 8:59am";
SimpleDateFormat format = new SimpleDateFormat("mm/dd/yyyy hh:mma");
format.setTimeZone(TimeZone.getTimeZone("America/New_York"));
try {
Date date = format.parse(dtStart);
Log.i("clock", date.toString());
System.out.println(date);
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(date.getTime());
cal.setTimeZone(TimeZone.getTimeZone("Asia/Kolkata"));
int chour = cal.get(Calendar.HOUR_OF_DAY);
int cminute = cal.get(Calendar.MINUTE);
int dd = cal.get(Calendar.DAY_OF_MONTH);
int mm =cal.get(Calendar.MONTH);
int yy =cal.get(Calendar.YEAR);
String mode="AM";
if(chour>12)
{
chour=chour-12;
mode="PM";
}
String mytime=Integer.toString(chour)+":"+Integer.toString(cminute)+" "+mode;
String mydate=Integer.toString(dd)+"/"+Integer.toString(mm)+"/"+Integer.toString(yy);
Log.i("clock", mytime);
Log.i("clock", mydate);
} catch (ParseException e) {
e.printStackTrace();
} catch (java.text.ParseException e) {
e.printStackTrace();
}

這裏我的時間是正確的,但日期是錯誤的。我預計28/11/2012.我無法追蹤我做錯了什麼地方?
