Patch from Ryouichi Matsuda

 An attached patch corrects problem of this bug and fractional second.


 The handling of time zone was as follows:

   (a) with time zone
       using  SimpleDateFormat("yyyy-MM-dd HH:mm:ss z")
   (b) without time zone
       using  SimpleDateFormat("yyyy-MM-dd HH:mm:ss")


 About problem of fractional second,
 Fractional second was changed from milli-second to nano-second
