Due to MySQL int Integer Type limitation, the biggest timestamp that can be stored is 2147487247 which is 01/19/2038 @ 4:14 am (UTC).

Trying to store later date/datetime will result in 500 exception.

Steps to reproduce
1. Create new Content Type with the date field.
2. Create a new content object from said Content Type, set the date to 2050-01-01 and publish it.

Result
HTTP 500 Internal Server Error
Database error
