[Zope] TAG for file date

Greetings, I have a database file that gets copied via a cron job at night. I would to display the new the new file date in an htlm document using Zope. What I would like is a tag that displays the date of a specific file. Is there such a dynamic tag? I am thinking something like <File-tag>copied-file</File-tag> Any help would be apprechiated.
