  |[WARNING] Your expected `at(...)` value does not match the job scheduled_at value
  |unless microseconds are removed. This precision error often occurs when checking
  |values against `Time.current` / `Time.now` which have usec precision, but Rails
  |uses `n.seconds.from_now` internally which has a usec count of `0`.
  |
  |Use `change(usec: 0)` to correct these values. For example:
  |
  |`Time.current.change(usec: 0)`
  |
  |Note: RSpec cannot do this for you because jobs can be scheduled with usec
  |precision and we do not know whether it is on purpose or not.
