Why doesn't git diff work between two dates? - eclipse

Question

I checked out a project from an internal GitLab server using Eclipse, then I pulled all the changes. When I view the history from Eclipse. (Team > show in history), it displays the full history of the project.
Now I go to the relevant project from the terminal.
/home/workspace/ProjectX/
I am trying to get the differences between 2 dates with the following command:
git diff --name-only master#{2015-10-10}..master#{2015-11-10} > /home/results/ProjectX/Changes.txt
It wont display any result for that. It displays:
warning: Log for 'master' only goes back to Tue, 10 Nov 2015.
How can I get all the differences in that date range?
In addition to that, how does Eclipse request its history from the remote server. If we can run the same command from the terminal, that should work.

Git parses dates like master#{2015-10-10} using your reflog, which doesn't appear to go back as far as you're searching. But, you can find commits for that date range anyway with rev-list:
git rev-list --since='2015-10-10' --until='2015-11-10' master
You want the files changes between the most recent and the oldest commit in that list, which we can get using head and tail. I'd like to use -n1 and --reverse, but --reverse applies after -n, so we can't.
first=$(git rev-list --since='2015-10-10' --until='2015-11-10' master | tail -1)
last=$(git rev-list --since='2015-10-10' --until='2015-11-10' master | head -1)
git diff --name-only $first..$last
Setting variables and duplicating the rev-list feels clumsy, but the pipe-y version I can come up with is sort of worse. It picks the first and last commits, converts the newline to a space using tr, replaces the new space with .. using sed, then passes the pair off to git diff.
git rev-list --since='2015-10-10' --until='2015-11-10' master | \
(head -n1 && tail -n1) | \
tr '\n' ' ' | \
sed 's/ /../' | \
xargs git diff --name-only
