`notify_credentials` has 2 ways of running.
1. The manual, one-off method which uses `--args_from_database` to specify what should be sent.
2. [The automated method](7316111b35/openedx/core/djangoapps/credentials/management/commands/notify_credentials.py (L157-L159)), which runs on a regular schedule, to catch anything which fell through the cracks.
The automated method does a certain amount of time/date math in order to calculate the entry point of the window based on the current runtime. This is, I assume, why it has some hardcoded logic; it's not at all simple to have a `cron`-run management command running on a regular cadence that can do the same time logic.
```py
if options['auto']:
options['end_date'] = datetime.now().replace(minute=0, second=0, microsecond=0)
options['start_date'] = options['end_date'] - timedelta(hours=4)
```
However, it is not ideal that the actual time window of 4 hours is hardcoded directly into `edx-platform`.
This fix
* creates an overridable `NOTIFY_CREDENTIALS_FREQUENCY` that defaults to 14400 seconds (4 hours).
* pulls that frequency into the quoted code
Using seconds allows maximum flexibility.

Open edX -------- This is the root package for Open edX. The intent is that all importable code from Open edX will eventually live here, including the code in the lms, cms, and common directories. If you're adding a new Django app, place it in core/djangoapps. If you're adding utilities that require Django, place them in core/djangolib. If you're adding code that defines no Django models or views of its own but is widely useful, put it in core/lib. Note: All new code should be created in this package, and the legacy code will be moved here gradually. For now the code is not structured like this, and hence legacy code will continue to live in a number of different packages.
