This bug is now blocking Prometheus (which I co-maintain) from transitioning to testing.
In the meantime, I see that there is a new release of moment-timezone.js upstream (0.5.34) which updates the IANA TZDB to 2021e, and would thus perhaps resolve the test failures that I see when trying to build the current 0.5.33 package: > Warning: 35/1394782 assertions failed (26711ms) Use --force to continue. The tweak to debian/control, which allegedly closes this bug, could then be made a more elegant "tzdata (>= 2021e)" My JS is pretty rusty these days, and I mostly only touch Go packages in Debian, so I'm hesitant to upload a 0.5.34 package (but may do so if this bug is going to stagnate).
