# Upstream's pub.dev archives record every directory entry with an epoch (0)
# timestamp.  dh_install preserves the mtime of the directories it copies, so
# the binary package would ship lib/ dated 1970-01-01 and lintian reports it as
# package-contains-ancient-file.  Stamp the installed directories with the
# source date instead (dh exports SOURCE_DATE_EPOCH from debian/changelog, so
# builds stay reproducible); no file content is affected.
