Actually, that doesn't look like a valid date format for HTTP headers
(refer to RFC 2616 for details).  It should look something more like
"Sat, 13 May 2000 22:37:47 GMT" (with no offset on GMT).

Whenever you are within double quotes, you are using a Python
expression, so <dtml-*> will no longer work.  Also, using ''
is a string literal, so you would have literally been setting
Last-Modified to "<dtml-var bobobase_modification_time>".  Try
something like:

  <dtml-call "RESPONSE.setHeader('Last-Modified', _['bobobase_modification_time'])>
