Description:
https://github.com/mysql/mysql-connector-j/blob/release/5.1/src/com/mysql/jdbc/TimeUtil.ja...

com.mysql.jdbc.TimeUtil#getDefaultTimeZone(boolean) 

   public static final TimeZone getDefaultTimeZone(boolean useCache) {
        return (TimeZone) (useCache ? DEFAULT_TIMEZONE.clone() : TimeZone.getDefault().clone());
    }

How to repeat:
   public static final TimeZone getDefaultTimeZone(boolean useCache) {
        return useCache ? DEFAULT_TIMEZONE.clone() : TimeZone.getDefault();
    }
