PB in sqlite 3.0.2 when define SQLITE_OMIT_DATETIME_FUNCS

I think sqlite3RegisterDateTimeFunctions should be in date.c

void sqlite3RegisterDateTimeFunctions(sqlite *db){
#ifndef SQLITE_OMIT_DATETIME_FUNCS
  static struct {
     char *zName;
     int nArg;
     void (*xFunc)(sqlite3_context*,int,sqlite3_value**);
  } aFuncs[] = {
    { "julianday", -1, juliandayFunc   },
    { "date",      -1, dateFunc        },
    { "time",      -1, timeFunc        },
    { "datetime",  -1, datetimeFunc    },
    { "strftime",  -1, strftimeFunc    },
  };
  int i;

  for(i=0; i<sizeof(aFuncs)/sizeof(aFuncs[0]); i++){
    sqlite3_create_function(db, aFuncs[i].zName, aFuncs[i].nArg,
        SQLITE_UTF8, 0, aFuncs[i].xFunc, 0, 0);
  }
#endif
}
