Get Am/PM value from Nullable TimeSpan
<p>I'm getting time from database received as  class TimeSpan. In order to diplay as Am/PM I switched it over to DateTime</p>

<pre><code> @string.Format("{0:hh:mm:ss tt}", new DateTime().Add(t.BegTime))
</code></pre>

<p>This worked.</p>

<p>As soon as I changed TimeSpan to allow Nulls it stopped working. Why? And how do I fix this?</p>
