def extract_from_attributes!(attrs, field, method = :local)
  parse_from_attributes(attrs, field, method).tap do |time|
    attrs.delete_if { |k, v| k.to_s =~ /^#{field}.+/ }
  end unless attrs.blank?
end

.parse_from_attributes(attrs, field, method = :local) ⇒ Object

Used for getting multifield attributes like those generated by a select_datetime into a new Time object. For example if you have following params={:meetup=>{:"time(1i)=>..."}} just do following:

Time.parse_from_attributes(params[:meetup], :time)
