datetime in Task doesn't match datetime in .task file

Please take a look at #345 . I would like to use vit inside a docker container. Unfortunately, the datetimes in Task objects do not necessarily match the true datetimes of tasks. To reproduce the issue, take the following steps:

1. Run set-up-container.sh (See the linked issue).
2. Once inside the container, run generate-dummy-install.sh and run the export commands that it tells you to.
3. Add debug.console(task._data) directly above line 233 of ./usr/lib/python3/dist-packages/vit/task_list.py and import vit.debug as debug to the top of that file.
4. Modify task 2 to have due date 2023-09-13 17:00:00.
5. Inspect the logs.
