We were not satisfied with the regular time selection widgets out there, so we wrote a quick wrapper for chosen.js to provide us with a way to select the time in as little as 2 keystrokes... rad!
<select data-placeholder="Choose time..." class="chzn-time"></select>
$('chzn-time').chosenTime();
.. that's it!
