A simpler way:
tar up all the files from september in $logdir
create two dummy files with dates
201209010000 beginning of September
201209305959 end of september
Code:
cd $logdir
touch -t 201209010000  /tmp/d1
touch -t 201209010000  /tmp/d2
# back the files we want
tar -cfv /tmp/mytarball.tar $(find . \( -newer /tmp/d1 -a ! -newer /tmp/d2 \) )
if [ $? -ne 0 ] ; then
   echo "tar failed"
   exit 1
fi
# the above traps all tar failures
# do something here to check read the tar file  I do not know what you want
# We could restore the tarball someplace and do a directory compare maybe

gzip /tmp/mytarball.tar 
# /tmp is not good longer term storage

mv /tmp/mytarball.tar.gz /someplace/safe
# delete the files
find . \( -newer /tmp/d1 -a ! -newer /tmp/d2 \) -exec rm {} \;

GIT-TAR-TREE(1) 						    Git Manual							   GIT-TAR-TREE(1)

NAME
git-tar-tree - Create a tar archive of the files in the named tree object SYNOPSIS
git tar-tree [--remote=<repo>] <tree-ish> [ <base> ] DESCRIPTION
THIS COMMAND IS DEPRECATED. Use git archive with --format=tar option instead (and move the <base> argument to --prefix=base/). Creates a tar archive containing the tree structure for the named tree. When <base> is specified it is added as a leading path to the files in the generated tar archive. git tar-tree behaves differently when given a tree ID versus when given a commit ID or tag ID. In the first case the current time is used as modification time of each file in the archive. In the latter case the commit time as recorded in the referenced commit object is used instead. Additionally the commit ID is stored in a global extended pax header. It can be extracted using git get-tar-commit-id. OPTIONS
<tree-ish> The tree or commit to produce tar archive for. If it is the object name of a commit object. <base> Leading path to the files in the resulting tar archive. --remote=<repo> Instead of making a tar archive from local repository, retrieve a tar archive from a remote repository. CONFIGURATION
tar.umask This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write bit. The special value "user" indicates that the archiving user's umask will be used instead. See umask(2) for details. EXAMPLES
git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -) Create a tar archive that contains the contents of the latest commit on the current branch, and extracts it in /var/tmp/junk directory. git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz Create a tarball for v1.4.0 release. git tar-tree v1.4.0^{tree} git-1.4.0 | gzip >git-1.4.0.tar.gz Create a tarball for v1.4.0 release, but without a global extended pax header. git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar Get a tarball v1.4.0 from example.com. git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar Put everything in the current head's Documentation/ directory into git-1.4.0-docs.tar, with the prefix git-docs/.
