> Currently dates that belong to Julian calendar (before Oct 15, 1582) are
> handled improperly by date/timestamp UDFs.
> E.g. DateFormat UDF:
> Although the dates are in Julian calendar, the formatter insists to print
> these according to Gregorian calendar causing multiple days of difference in
> some cases:
>
> {code:java}
> beeline> select date_format('1001-01-05','dd---MM--yyyy');
> +----------------+

> | 30---12--1000 |

> I've observed similar problems in the following UDFs:
> * add_months
> * date_format
> * day
> * month
> * months_between
> * weekofyear
> * year
