by default datetime\_select allows the user to input any date and time  
they want.

Is there a way it can only allow a user to select an hour between 8AM  
and 6PM and only allow them to choose the top of the hour (:00) and  
the half hour (:30) for the minute?

Hi, Phil.

I haven’t yet found a way to show a 12-hour clock unless you try the  
Flextimes plugin ([http://flextimes.rubyforge.org/](http://flextimes.rubyforge.org/)), which I haven’t  
tried yet.

The second part of your question is easy to answer. Use  
the :minute\_step=\>nn option, where nn is the number of minutes you  
want for each “step”. In your case, set to to 30.
