Bug#964155: libcalendar-simple-perl breaks libtemplate-plugin-calendar-simple-perl autopkgtest: not ok 1 - correct output for Jan 1970

Dear maintainer(s),

With a recent upload of libcalendar-simple-perl the autopkgtest of
libtemplate-plugin-calendar-simple-perl fails in testing when that
autopkgtest is run with the binary packages of libcalendar-simple-perl
from unstable. It passes when run with only packages from testing. In
tabular form:

                                          pass            fail
libcalendar-simple-perl                   from testing    2.0.0-1
libtemplate-plugin-calendar-simple-perl   from testing    1.00-1
all others                                from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of
libcalendar-simple-perl to testing [1]. Due to the nature of this issue,
I filed this bug report against both packages. Can you please
investigate the situation and reassign the bug to the right package?
