There are a couple of strange things with the command line:
Code:
find /tmp/w/ -type f   -newermt '2014-03-01' ! -newermt '2014-04-01' | xargs tar -czvf files03.tar

  1. By convention, a gzipped file should have .gz as its final suffix; not .tar.
  2. The reason for using xargs command (or find ... -exec command +) is to run the given command as many times as are needed to meet ARG_MAX limitations. But, if you invoke tar multiple times with the -c option, your output file will be recreated from scratch on each invocation (wiping out the data stored in the previous invocation). You could get around that problem if you remove your output file before you start and use tar -r instead of tar -c, but on many systems you can't use the -z option with -r.
If you use pax instead of tar to create the archive, you can feed it the names of files to be processed through its standard input instead of worrying about command line argument length limits. So you might want to try something more like:
Code:
find /tmp/w/ -type f -newermt '2014-03-01' ! -newermt '2014-04-01' | pax -w | gzip > files03.tar.gz

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/.
