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
