The OpenCMS taglib provides tags, but also functions. You can see their definition in the WEB-INF/opencms.tld file, the functions themselves are provided by the CmsJspElFunctions class.
Just declare the taglib as usual:
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>
cms:vfs
Provides access to VFS (Virtual File System), returns an instance of org.opencms.jsp.util.CmsJspVfsAccessBean. Example:
${cms:vfs(pageContext).context.locale}
cms:convertDate
Allows conversion of Long values to Dates. For example to display the time of last modification of a page:
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %> <%@ taglib prefix="f" uri="http://java.sun.com/jsp/jstl/fmt" %> ... <f:formatDate value="${cms:convertDate(cms:vfs(pageContext).resource[cms:vfs(pageContext).context.uri].dateLastModified)}" pattern="yyyy-MM-dd HH:mm:ss" />
