Hi, it was my fault.

My wrong code was:
========================================
   public TimeOfDay* getTime() {
     char[] timestring = "10:00:00"; // for test
     FullDate fd;
     parseTime(timestring, fd);
     return *fd.val.time();
   }
========================================

Today I have changed it to:
========================================

   public TimeOfDay* getTime() {
     char[] timestring = "10:00:00"; // for test
     FullDate fd;
     parseTime(timestring, fd);
     TimeOfDay* ret = new TimdOfDay();
     *ret = fd.val.time();
     return ret;
   }
========================================

Now it works properly.
