Is git mktag supposed to accept git cat-file input?

Hi,

I am doing some experimenting with git-mktag, and was looking into the format it expects on input.

Should this sequence of commands work?

kalki:[~]% mkdir /tmp/gittest; cd /tmp/gittest
kalki:[/tmp/gittest]% git init
Initialized empty Git repository in /tmp/gittest/.git/
kalki:[/tmp/gittest]% echo "test" > test
kalki:[/tmp/gittest]% git add test
kalki:[/tmp/gittest]% git commit -m "commit-test"
[master (root-commit) c0ae36f] commit-test
 1 file changed, 1 insertion(+)
 create mode 100644 test
kalki:[/tmp/gittest]% git tag -m "tag-test" tag-test
kalki:[/tmp/gittest]% git cat-file -p e619

tag tag-test

tag-test2 kalki:[/tmp/gittest]% git mktag < tag-test2 error: char112: missing tag timestamp fatal: invalid tag signature file kalki:[/tmp/gittest]% git --version git version 1.7.9.5

The error message related to the timezone / timestamp being incorrect but I can't see what the problem is.

Any advice appreciated.

Please CC me as I may miss your reply.

Thanks, Anand
