Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

$ git checkout 1.0.x
$ git pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

$ git cherry-pick -m1 d171c871baa13bdfd2fe14c8a5918190314825bb

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

$ git commit -am 'Backport PR #32152: TST: add test for get_loc on tz-aware DatetimeIndex'

4. Push to a named branch :

git push YOURFORK 1.0.x:auto-backport-of-pr-32152-on-1.0.x

5. Create a PR against branch 1.0.x, I would have named this PR:

"Backport PR #32152 on branch 1.0.x"

And apply the correct labels and milestones.

Congratulation you did some good work ! Hopefully your backport PR will be tested by the continuous integration and merged soon!

If these instruction are inaccurate, feel free to suggest an improvement.

@simonjayhawkins may need a manual backport
