Code review comment for ~ginggs/britney:moment-timezone.js

This is currently blocking the migration of the new version of itself, moment-timezone.js/0.5.32+dfsg1-2+2021a, from -proposed.

I have spoken to one of the uploaders of the Debian package and confirmed this is a test failure only. 0.5.32+dfsg1-2+2021a includes the data for 2021, but the tests were not yet updated to match. The next upstream version, 0.5.33, will fix the tests.
