I have just uploaded a new tzdata to fix this issue, switching back from
the 'fat' format. I am therefore cloning the bug instead.

python3-dateutil is aware of this issue for many time, but there hasn't
been any recent activity:
https://github.com/dateutil/dateutil/issues/1059

This needs to be fixed anyway by 2038 to avoid any breakage by that
date.
