EBR Time.now display problem

As a new RoR user I need a little help please. I am using Mac OS X 10.4.9 and
Ruby version 1.8.6 (powerpc-darwin8.8.0) RubyGems version 0.9.2 Rails version 1.2.3
Active Record version 1.15.3 Action Pack version 1.13.3 Action Web Service version 1.2.3
Action Mailer version 1.3.3 Active Support version 1.4.2

In one of my layouts I have the following:
<p> This is a listing of all the records <br />
  in the contacts database <br />
  as of <%= Time.now %></p>

but it displays like this:

This is a listing of all the records
in the contacts database
as of Thu Jun 07 12:49:59 -0400 2007

All the docs I have read (Programming Ruby, Agile Web Dev)
say it should display EDT instead of the offset from UTC :

Thu Jun 07 12:49:59 EDT 2007

What can I do to track down why this is happening so I can fix it.
TIA for your advice.

respect....
