How to compare a date?

I have a container with a startDate and an endDate field.

I want to show the container if curent date is in between those dates.

How can I compare with current date? (System.currentTimeMillis())

I can find some java code doing by using java code (scriplet) (box_news.inc).

But how can we do this by using taglibs (jahia,jstl,struts)?

...

<content:dateField ..../>

...

<c:if test="${ ????? }">

// Show container fields...

</c:if>

...
