In Git v1.5.4.1, Documentation/git-tag.txt advises: > To set the date used in future tag objects, set the environment > variable GIT_AUTHOR_DATE to one or more of the date and time. The > date and time can be specified in a number of ways; the most common > is "YYYY-MM-DD HH:MM". But this does not work because git tag uses GIT_COMMITTER_DATE instead. In builtin-tag.c: > header_len = snprintf(header_buf, sizeof(header_buf), > "object %s\n" > "type %s\n" > "tag %s\n" > "tagger %s\n\n", > sha1_to_hex(object), > typename(type), > tag, > git_committer_info(IDENT_ERROR_ON_NO_NAME)); i.e. it does not call git_author_info. The backdating section was added to git-tag.txt in 5040beff, and builtin-tag.c already used git_committer_info at that time. The older git-tag.sh used tagger=$(git-var GIT_COMMITTER_IDENT). Thus it seems the bug is in the documentation, not in the code. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
