Track times
I implement feature request https://github.com/pandas-dev/pandas/issues/32682 but if someone has more experience with pytables consider these changes.

The h5 files generated with track_times=False has the same md5 hashes, that is covered in the unit test as well as the fact that the hashes are not the same with track_times=True

- [x] closes #32682
- [x] tests added / passed
- [x] passes `black pandas`
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [x] whatsnew entry
