Date Stamp In Vim Options

[jamesannan]

I would like to have a way of inserting the date in vim, in my own preferred format. I can use
:r !date
and get the standard date format, but when I try
:r !date +"%Y %m %d" or whatever, the % get replaced by the current filename.

Ok, this may seem like more of a vim question than a zaurus question, but all the stuff I find on the web refers to strftime which my vim (from here: http://sharpromfeed.home.linuxtogo.org/feed/) does not seem to have. I also see lots on the web about "escaping" various characters to stop vim substituting them (and I've tried a lot of random things) but nothing that appears to covers this situation. I'd be grateful fo a hint.
