Probably not, it is usually not a good idea to allow anyone to run
arbitrary ruby code on your server, though there are ways to make it
somewhat safe... you never know :)

Anyway, to get around it, you can fire up irb on your own computer and do this:

irb> require 'rubygems' #=> true
irb> require 'haml' #=> true
irb> require 'date'
irb> haml_text =<<ENDDOC
irb> %p
irb>   Date/Time:
irb>   - now = DateTime.now
irb>   %strong= now
irb>   - if now > DateTime.parse("December 31, 2006")
irb>     = "Happy new " + "year!"
irb> ENDDOC
irb> haml = Haml::Engine.new(haml_text)
irb> puts haml.render

And you should get:

<p>
  Date/Time:
  <strong>2008-03-10T22:40:43+11:00</strong>
  Happy new year!
</p>
=> nil
