If you are using bcp to load dates, you'll want to know about this.  

Using freebcp to load this file:

$ head ivr.dat
1063195\03-JAN-00\271.54319615\21\0\21\\\\\
1063195\04-JAN-00\266.56002764\21\0\21\\\\\

into a table whose second column is smalldatetime, I get 

1> select count(*), year(AsOf), min(AsOf), max(AsOf) from ivr group by 
year(AsOf) order by year(AsOf)
2> go

 ----------- ----------- -------------------- --------------------
         260        1900   Jan 3 1900 12:00AM  Dec 29 1900 12:00AM

If the date string ends in '-99' I get 1999, if '-01' then 2001.  But '-00' 
is a trip to This Old House.  

The error is in src/tds/convert.c::store_year().  Patch attached.  

store_year(int year, struct tds_time *t)
{

        if (year <= 0)  // should be < 0
                return 0;

        if (year < 100) {
                if (year > 49)
                        t->tm_year = year;
                else
                        t->tm_year = 100 + year;
                return (1);
