This is Vim-only: put below user command definition into your vimrc:
com! -bar Timestamped :exec 'file '. fnameescape(printf('%s-%s.%s', expand('%:r'), strftime('%Y%m%d_%H%M%S'), expand('%:e')))

Then
vim +Timestamped filename.txt

will modify the filename after starting to edit "filename.txt".
:file reuses the same buffer and creates a new buffer for the original file.
The new (timestamped) file, although not written yet, is not considered modified.
