no issue
- we store dates without milliseconds in the database
- our test environment does not use our model layer to insert data, this is related to https://github.com/TryGhost/Ghost/issues/7196
- so it can happen that the test env inserts unix timestamps instead of a formatted string
- e.g. adding data via the model layer (e.g. via the API) the format is always normalised to `YYYY-MM-DD HH:mm:ss`
- if we fetch the date from the database, we have a hook which sorts out knex returning different formats for dates
- this hook wraps the returned date into a UTC moment date, but adds the current milliseconds on top
- which can collide in tests when you have specific assertions
- use `startOf` to ignore milliseconds
- furthermore: remove the mentionings of `pg` (postgres)
