[Zope] bobobase_modification_time syntax

Hi everyone, I've grepped through the source and consulted the ZQR, but I still haven't figured out how to use bobobase_modification_time. I've got a directory with a file object, and I'd like index_html to display when that file object was last modified. I've tried all manner of syntax combinations, but I can't get it to refer to the modification time of a given object and not just the modification time of index_html.
