VIM: Preserve File Date with Touch

I had a single file I needed to modify but didn’t want to modify the date of the file.  It was a minor change to the file, so I wanted to maintain the file date for posterity.  In any case, I learned the vim does not provide this functionality, but touch would and quite easily.  With that said, I am familiar with touch and use it quite often, but the following approach proved direct and resolved the problem.

touch -r myfiletoedit timestamp
vim myfiletoedit
touch -r timestamp myfiletoedit

From the man pages:

-r, --reference=FILE
use this file’s times instead of current time
