instance method
minus_with_coercion
Ruby on Rails edge
Since v3.0.20Signature
minus_with_coercion(other)Time#- can also be used to determine the number of seconds between two Time instances. We’re layering on additional behavior so that ActiveSupport::TimeWithZone instances are coerced into values that Time#- will recognize

# Prefer an exact rational difference: Float (to_f) cannot represent every
# microsecond, so sub-second DateTime values lost precision (same class of
# issue as Time.at with DateTime). The difference is returned as a Float
# to match Time#-(Time) and ActiveSupport::TimeWithZone#-(DateTime).
