Add this line just before (vm-update-summary-and-mode-line):

(vm-discard-cached-data)

I think what you really want to know is how old the message is.

My fantasy is to have a summary option that gives you the age of
the message in relative units like "yesterday", "a few minutes
ago", etc. instead of having to deal with timezone translations
and whatnot.

The problem with this is that the summary gets out of date as
time passes and therefore needs to be updated asynchronously.
This in turn means that I'd need to use my interval timer
package, and maybe assign a timer to every message.  This would
undoubtedly make Emacs crash every three minutes, and make me one
of America's Most Wanted. :-)
