Error - ORA-01861: literal does not match format string

I modified my OCIBindPos test program a bit to execise some cases.

I'm doing a

drop table arraytest;
create table arraytest (field1 varchar2(20), D FLOAT, L LONG, T DATE ,M INTEGER)
;
select * from arraytest;
quit;

and when running the following code on it, I'm getting:

#include <fcntl.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <io.h>
#include <stdio.h>
#include <string.h>
#include <oci.h>
#include <ocidfn.h>

#define BIGBUF 100000

char bigdata[BIGBUF];
void checkerr (OCIError * errhp, sword status);

const char insertSQL[] = "insert into arraytest values ( :1, :2 ,:3, :4,:5)";


char *strColVal[] = { "ABC", "111.1", bigdata, "2009-07-17-16.05.31", "56"};
