  def set_times
    self.showing_date = self.start_time.strftime("%A, %B %d, %Y") unless self.start_time.nil?
    self.start_date = self.start_time.strftime("%-I:%M%p") unless self.start_time.nil?
    self.end_date = self.end_time.strftime("%-I:%M%p") unless self.end_time.nil?

  def set_dates
    self.start_time = DateTime.strptime("#{start_date} #{showing_date} #{Time.now.zone}", "%I:%M%p %A, %B %d, %Y %z")
    self.end_time = DateTime.strptime("#{end_date} #{showing_date} #{Time.now.zone}", "%I:%M%p %A, %B %d, %Y %z")
  end

end

I'm starting to give up on the idea of seperate date and time fields so I've started converting my app to use a single datetime field/db column to see if that is a better option for me.

I'm now on the lookout for a datetime picker since I need the datetime to be in a textfield but I don't think the date part and time part can be split easily. Before I was using a datepicker on a textfield for the date and dropdowns for the time.

In the end I used a merged datetime text_field and the code here: codegram/date_validator#25 (comment)
