Current Behavior

The test df_time_operations.py is failing due to type errors. The issue has been traced to a pd.concat call in time_operations.py where a column is trying to be added, but instead, rows are added with the column.

Expected Behavior

The test should pass.

Steps To Reproduce

Run pytest df_time_operations.py in the tests directory.

Environment

- OS: Ubuntu 20.04
- pip environment (can be retrieved with `pip list`):
  - pandas 1.4.4
  - numpy 1.21.5
  - scipy 1.8.0

Anything else?

None.

This seems to be at least partly due to the new version of pandas. Looking into this now.
