Subject: How to get just hour and minute?

I have a Ruby project with a User object that consists of various
fields (attributes). Two of these are preferredStart and preferredEnd
and were configured with the "... script/generate scaffold ..."
command to have type "time".  When I visit the resulting "New User"
page, the input for those two fields has date and time. In other
words, the user could select a month, date and year in addition to
hour, minute and second for preferredStart and preferredEnd. The
relevent code from the view/new_user.html.erb is:

  <p>
    <%= f.label :preferredStart %><br />
    <%= f.datetime_select :preferredStart %>
  </p>
  <p>
    <%= f.label :preferredEnd %><br />
    <%= f.datetime_select :preferredEnd %>
  </p>
  <p>

Is there a way to limit the input selection to simply hour and
minute?  I tried, for instance:

<%= f.datetime_select :preferredStart, prompt => {:hour =>
true, :minute => true} %>

That did not have the intended effect, though.
