Hi,
I got the following bugreport which makes the submitter very confused:

While the year 2000 (y2k) problem is not an issue for us, all Linux
implementations will impacted by the year 2038 (y2.038k) issue. The Debian
Project is committed to working with the industry on this issue and we will
have our full plans and strategy posted by the first quarter of 2020.
