Perhaps if we add a dependency on tzdata and set TZDIR, as is done for
‘duplicity’ for instance, the tests would run?

Anyway this probably shouldn’t block the whole series!

Please use ‘license:perl-license’ here.

You can make it:

   (license:fsf-free "file://COPYING"
                     "Open Software License 2.0")

OK with these changes, thank you!
