def self.remove_time_from_ancestors(entity, time)
  
  entity.ancestors_with_type(:phrase).each do |a|
    
    next if !a.has?(:time)

    unless a.get(:time) == time
      return true
    end
    
    a.unset(:time)
    
  end
  
  false

.time(entity, options = {}) ⇒ Object

Return a DateTime object representing the date/time contained within the entity, using Ruby’s native date/time parser. This extractor is suitable for the detection of well-structured dates and times, such as 2011/02/03 5:00.

Options: none.
