def coerce(other)
  logger.trace { "Coercing #{self} as a request from #{other.class}" }
  return unless other.respond_to?(:to_zoned_date_time)

  zdt = to_zoned_date_time
  [other.to_zoned_date_time(zdt), zdt]
end

#minus_with_temporal(other) ⇒ ZonedDateTime, ... Also known as: -

Extends #- to allow subtracting a TemporalAmount or any other date/time class that responds to #to_zoned_date_time.

Subtractions with another object of the same class (e.g. Time - Other Time, or DateTime - Other DateTime) remains unchanged from its original behavior.

Examples:

Time - Duration -> ZonedDateTime

zdt_one_hour_ago = Time.now - 1.hour

Time - ZonedDateTime -> Duration

java_duration = Time.now - 1.hour.ago

Time - Numeric -> Time

time_one_hour_ago = Time - 3600

Time - Time -> Float

one_day_in_secs = Time.new(2002, 10, 31) - Time.new(2002, 10, 30)

Parameters:

Returns:

  • (ZonedDateTime) —

    If other is a TemporalAmount

  • (Duration) —

    If other responds to #to_zoned_date_time

  • (Time) —

    If other is a Numeric

  • (Float) —

    If other is a Time
