Schedule date does not appear as a date filter in Views.

Problem/Motivation

I had to do some digging to see that this isn't technically a bug in this module so much as it is a bug in Drupal core. I don't claim to completely understand, but my take on this is:

Drupal 8 has taken a major step backwards in date handling, expecially for Date Ranges. Although Daterange fields added through the UI show in Views as proper date filters; when a daterange field is added through code to a custom entity; it appears to Views as a string field as far as filtering. #2848908: Views treats datetime fields like strings when filtering

There is a work around as it may be years before Drupal core gets this fixed. I'll submit a patch in the next comment.

Steps to reproduce

Proposed resolution

Add well known work around to basically override the default string handling that gets assigned to the field as a Views filter - and force it to be a date filter.

Remaining tasks

Tests?

User interface changes

This change will provide the proper date filter options such as >, <, between, etc.

API changes

None.

Data model changes

None.
