Just in case anyone is interested:

I've just posted ZDIR.COM to my downloads.

This is a little tool whose primary function is to list the content of a .ZIP
file in a simple/nice DOS "DIR" format.

(I'm sure you're now thinking "what does this have to do with DosBox")

ZDIR has a capability I specifically added for, and use within DosBox.
It can TOUCH (set timestamp) files within the .ZIP archive!

During my DDS years, I got in the habit of setting the times of distribution
files for the various DDS software projects to the Version of that product.
eg: Files in MC323.ZIP (Version 3.23 of my Micro-C compiler) would have a
timestamps of 03:23:00

But.. DosBox DOES NOT support INT 21-5701 - which means you can't easily set
a file timestamp, and my TOUCH.COM tool doesn't work!

So now, I can use something like: ZDIR MC323 *=3:23:0
on the MC323.ZIP that I create for distribution.
