ERR: better error reporting for failing parsing in timedelta/timeseries #10720
closes #10720 

Why did you close this one?
 Some advice:
- always work on a branch and not in master for a PR (so this one is better than #10884, I can reopen this one if you want)
- always update with the latest upstream before starting a new branch (you have still some old commits of a previous pr):
  
  ```
  git checkout master
  git fetch upstream
  git merge upstream/master --ff-only
  git checkout -b new_branch
  ```
  
  or now if you already started a branch, rebase it on master:
  
  ```
  git fetch upstream
  git rebase upstream/master
  ```
 Ohh i closed the other one because i wanted to rebase. Thanks for the tip

 Can you reopen this one instead and close the other one?
 Ok - so that attempt passed, any got any feedback about whether it's ready to be merged or does it need some more work?
 Seems ready 
 @springcoil this doesn't do anything. as you didn't actually change any code except for the tests. So this fails. And it still is not rebased on master.

```
In [1]: td = pd.Series(['May 04', 'Jun 02', ''], index=[1,2,3])

In [3]: pd.to_datetime(td,format='%b %y', errors='raise') 
ValueError: time data '' does not match format '%b %y' (match)
```
 Ok will fix that
