TimeZones has a strange heisenbug where it will sometimes fail to build the TZ data, often appearing in headless systems such as CI and documentation generation. Apparently a workaround is to explicitly call Pkg.build() after instantiation to ensure a successful build, as noted by @iamed2 in https://github.com/JuliaTime/TimeZones.jl/issues/331#issuecomment-1051347453.
