Where is the Rails method that converts data from `datetime_select` into a DateTime object?

Answer 1

Had to do something very similar, and ended up using this method:

def time_value(hash, field)
  Time.zone.local(*(1..5).map { |i| hash["#{field}(#{i}i)"] })
end

time = time_value(params, 'start_time')
