Android SQLite Date Format - สอบถามเรื่อง Calendar.HOUR_OF_DAY ครับ ผมบันทึก 17:30 แต่พอเข้าไปดูมันกลายเป็น 05:30 แก้ไขยังไงดีครับ

Calendar cal = Calendar.getInstance();
Calendar new_cal = Calendar.getInstance();
                                                                      							sTime = (String) android.text.format.DateFormat.format("hh:mm",cal.getTimeInMillis());
							String[] time =sTime.split(":");
							String h = time[0];
							hour = parseInt(h);
							String m = time[1];
							minute = parseInt(m);
							sDate = (String) android.text.format.DateFormat.format("yyyy-MM-dd" ,cal.getTimeInMillis());
							String[] date =sDate.split("-");
							String d = date[2];
							String y = date[0];
							String mo = date[1];
							day = Integer.parseInt(d);
									new_cal.set(Calendar.HOUR_OF_DAY, 17);
									new_cal.set(Calendar.MINUTE, 30);
									new_cal.set(Calendar.YEAR, Integer.parseInt(y));
									new_cal.set(Calendar.MONTH, Integer.parseInt(mo)-1);									
									new_cal.set(Calendar.DAY_OF_MONTH, day);	
									Log.d("swf", (String) android.text.format.DateFormat.format("yyyy-MM-dd hh:mm",new_cal.getTimeInMillis()));
									dateTime = (String) android.text.format.DateFormat.format("yyyy-MM-dd hh:mm",new_cal.getTimeInMillis());

				        			Log.d("sql", sql_medicine);
				        			mDb.execSQL(sql_medicine);
