-------------------------------------
[~jcamachorodriguez]: as far as I know we've already tried this patch out at
customer's side, so after a green run we can merge this in my opinion
I've let some comments on PR, regarding timezone changes, which is not 100%
obvious to me, please check the comments on the following files:

> Hive recently moved its processing to the proleptic calendar, which has
> created some issues for users who have dates before 1580 AD.
> HIVE-22405 extended the column vectors for times & dates to encode which
> calendar they are using.
> This issue is to support proleptic calendar in ORC, Parquet, and Avro, when
> files are written/read by Hive. To preserve compatibility with other engines
> until they upgrade their readers, files will be written using hybrid calendar
> by default. Default behavior when files do not contain calendar information
> in their metadata is configurable.
