Rails - Jul 2006 - Auto-populating time portion of a datetime field from a form

I see that if I use the date_select helper in my view, then in the 
generated page, my selects are named obj[datetime_field(1i)] (and 2i and 
3i for the other parts).  These auto-populate the date portion of my 
datetime_field.

I have another datetime field that I''m presenting the time from and I 
would like to use a similar scheme to autopopulate it.  Currently, I''ve
used the :prefix option to select_hour/minute/second to get the 
parameter name set correctly, but I end up with a hash with keys
''hour'',
''minute'' and ''second''.  I can definitely
handle this, but was wondering,
can I just use 4i, 5i, 6i to index into the time portions of a datetime 
field?

Thanks,
Wes

Here''s what I ended up with after reading through the source of 
date_helper.rb:

<%= select_hour(@current_job.StartTime, :hour_format => "12",
:prefix =>
''current_job[StartTime(4i)]'', :discard_type => true) %>:

<%= select_minute(@current_job.StartTime, :prefix => 
''current_job[StartTime(5i)]'', :discard_type => true) %>:

<%= select_second(@current_job.StartTime, :prefix => 
''current_job[StartTime(6i)]'', :discard_type => true) %>

Seems to be posting correctly - now some other problem is occurring.

Clear as mud :).
