This is a very long way round for a shortcut (though it does have the 
merit of working). Why not just

def handler(req):
      req.content_type = "text/plain"
      req.send_http_header()
      curtime = strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime())
      req.write(str(curtime))
      return apache.OK

Or even

def handler(req):
      req.content_type = "text/plain"
      req.send_http_header()
      req.write(strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime()))
      return apache.OK
