I don't know why you'd want to run 'date' instead of Time.now from within 
Ruby, but the one reason I can think of is that Capistrano's #run isn't the 
equivalent of #system -- it runs a command on the remote system. I'm guessing 
the point here is to do something with the remote system's date, specifically. 
In that case, `date` is useless, as backticks run commands locally.
