+<p>This function can take a number poorly-formed date formats and convert them into something useful. It also accepts well-formed dates.</p>
+<p>The fuction will return a Unix timestamp by default. You can, optionally, pass a format string (the same type as the PHP date function accepts) as the second parameter. Example:</p>
+
+<code>$bad_time = 199605<br />
+<br />
+// Should Produce: 1996-05-01<br />
+$better_time = nice_date($bad_time,'Y-m-d');<br />

+$bad_time = 9-11-2001<br />
+// Should Produce: 2001-09-11<br />
+$better_time = nice_date($human,'Y-m-d');</code>
