protected static Date parseJsonDate(String date) {

  Matcher m = DATE_PATTERN.matcher(date);
  if (m.matches()) {
    long time = Long.parseLong(m.group(1));
    long zone = 0;

    if (m.group(2) != null && m.group(2).length() > 0)
      zone = Integer.parseInt(m.group(2)) / 100 * 1000 * 60 * 60;

    return new Date(time + zone);
  }
 
  logger.error("parseJsonDate failed: " + date);
