While working on reproducible builds for openSUSE, I found that
our perl-DBD-MariaDB package failed tests with

> 2038-01-20  0:00:08 0 [ERROR] This server doesn't support dates later than 2038

To reproduce:
osc co openSUSE:Factory/perl-DBD-MariaDB && cd $_
osc build --noservice --trust-all-projects --vm-type=kvm \
  --alternative-project=home:bmwiedemann:reproducible \
  --build-opt=--vm-custom-opt="-rtc base=2038-01-20T00:00:00" \
  openSUSE_Tumbleweed x86_64


Background:
As part of my work on reproducible builds for openSUSE, I check that software
still gives identical build results in the future.
The usual offset is +16 years, because that is how long I expect some software
will be used in some places.
This showed up failing tests in our package build.
See https://reproducible-builds.org/ for why this matters.
