Hi!
While working on the “reproducible builds” effort [1], we have noticed
that unicode-data could not be built reproducibly.
The attached patch sets TZ=UTC before calling unzip, ensuring that
the modification time of the extracted files will not vary depending
on the timezone of the build enviromnent. Once this patch is applied,
unicode-data can be built reproducibly.
