Best way to insert timestamp in Vim?

http://kenno.wordpress.com/2006/08/03/vim-tip-insert-time-stamp/

Tried it out, it works on my mac:

:r! date

produces:

Thu Sep 11 10:47:30 CEST 2008

This:

:r! date "+\%Y-\%m-\%d \%H:\%M:\%S"

produces:

2008-09-11 10:50:56

To make it work cross-platform, just put the following in your vimrc:

nmap <F3> i<C-R>=strftime("%Y-%m-%d %a %I:%M %p")<CR><Esc>
imap <F3> <C-R>=strftime("%Y-%m-%d %a %I:%M %p")<CR>

Now you can just press F3 any time inside Vi/Vim and you'll get a timestamp like 2016-01-25 Mo 12:44 inserted at the cursor.

For a complete description of the available parameters check the documentation of the C function strftime().
