# this sucker takes care of validating datetime fields before rails gets there and
# messes everything up. it should preserve the local time zone from the user input, 
# and check for nil. takes date strings of the format m/d/yyyy m:h (am/pm)

# this goes in the model
validates_with DateTimeValidator, :fields => [:add_date]

# this goes in some place like lib/date_time_validator.rb
class DateTimeValidator < ActiveModel::Validator
