Thanks, I ended up using a modified version of that command:

vim -c "exec strftime('silent edit fname-%Y%m%d_%H%M%S.txt')|put +|normal 1G"

Now I can paste directly to a new instance of vim with a ready-made filename! I'm using this with AutoHotKey (tied to Ctrl-Win-V), so I had to escape the %s with backticks (`):

Run "C:\Program Files (x86)\Vim\gvim.exe.lnk" -c "exec strftime('silent edit filename-`%Y`%m`%d_`%H`%M`%S.txt')|put +|normal 1G"
