把Catalina的字符串格式转化为日期格式
public static void distinctCoords(LinkedList list,String date,String imei,double GpsLat,double GpsLng){
Date parse=null;
DateFormat df = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy", Locale.US);
try {
parse=df.parse(date);
} catch (ParseException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
