Hi, I fixed the problem myself.
The thing lies in src/freetds/convert.c, in the function
tds_convert_datetime
I fixed the problem by changing it :
TDS_INT tds_convert_datetime(int srctype,unsigned char *src,int
desttype,unsigned char *dest,TDS_INT destlen)
{
TDS_INT dtdays, dttime;
time_t tmp_secs_from_epoch;

        switch(desttype) {
                case SYBCHAR:
                case SYBVARCHAR:
                /* FIX ME -- This fails for dates before 1902 or after 2038
*/
                        if (destlen<0) {
                                        memset(dest,' ',30);
                        } else {
                                memset(dest,' ',destlen);
                        }
                        if (!src) {
                                *dest='\0';
                                return 0;
                        }
                        memcpy(&dtdays, src, 4);
                        memcpy(&dttime, src+4, 4);
                        /* begin <lkrauss AT wbs-blank.de> 2001-10-13 */
                        if (dtdays==0 && dttime==0) {
                                *dest='\0';
                                return 0;
                        }
                        /* end lkrauss */
                        tmp_secs_from_epoch = ((dtdays - 25567)*24*60*60) +
(dttime/300);
                        if (destlen<20) {
                                strftime(dest, destlen-1, "%b %d %Y
%I:%M%p",
                                (struct tm*)gmtime(&tmp_secs_from_epoch));
                                return destlen;
                        } else {
                                file://strftime(dest, 20, "%b %d %Y
%I:%M%p",
                                // Patch by s. sonnenberg-carstens to fix
some nasty conversion errors
                                strftime(dest, 20, "%Y-%m-%d %H:%M:%S",
                                (struct tm*)gmtime(&tmp_secs_from_epoch));
                                return (strlen(dest));
                        }
                        break;
                case SYBDATETIME:
                        memcpy(dest,src,sizeof(TDS_DATETIME));
                        return sizeof(TDS_DATETIME);
                        break;
                case SYBDATETIME4:
                        break;
                default:
                        return TDS_FAIL;
                        break;
        }
        return TDS_FAIL;
}

After applying the patch, the data comes in the same form as it is displayed
by the QueryAnalyzer.
This patch applies to 0.53pre3

Subject: [freetds] DATETIME problem


We defined some tables with DATETIME types.
If we fetch the data via the SQLAnalyzer we see the correct time,
"12.12.2001:23:34:34.045" for example.
If we do so with PHP's mssql_query, the seconds are missing.
We use freetds 0.53pre3.
What is wrong ?
