Ruby 2.7 added sub seconds to Time#inspect and separated it from Time#to_s.

Rails also added sub seconds to ActiveSupport::TimeWithZone#inspect.

This is particularly helpful when multiple time objects are created in a short interval. For e.g., when executing imports in parallel, or when we need to assert time differences in our test cases.

#### Summary

As seen above the nsec part is not ignored anymore when we use inspect. This is useful for finer comparisons, assertions and usage with time across databases and systems.
