title: Ruby Gem Calendar Date Select
body: <p>Hey, I'm having trouble with the time portion of the Calendar Date Select gem. The following code limits the date to any day after/greater than today. I need to do this for time, limiting the user to a time that is 24 hours or greater than from now. I can't figure out if the code used in the :valid_date_check is SQL, or Javascript or what. Google and IRC can't figure it out either. Does anyone either have experience with this gem, and had success doing this, or know what the code is so I can go about implementing it myself.</p>
  
  <pre><code>&lt;%= calendar_date_select_tag "time", "", :popup =&gt; :force, :time =&gt; true, :valid_date_check =&gt; "date &gt; (new Date()).stripTime()" %&gt;
  </code></pre>
