Back in the 90's there was a utility called Zipdate that allowed you to specify a ZIP file or a directory, and it would modify the date attribute of the ZIP files to correspond to the newest file contained in the ZIP.
That is, you might have a ZIP file named Tools.zip, with a "modified" timestamp of 07/14/2009. However, the latest tool in the zip file might be dated 03/12/2004. You would prefer the ZIP date to match the 2004 date, so that at a quick glance you know how "old" the files contained in the zip are.
I've done a quick search here and on the Net, and even downloaded a new version of the PKZIP utilities and haven't found this capability. The Zipdate util from SIMTEL only seems to handle short file names...
Does anyone know if any of the newer archive utilities provides this function, or could such a thing be coded easily?
