dynamic date to title tag to give SE impression content is new?

[etard]

So, one of my clients had an SEO company tell them "installing a script that would add a dynamic date to the title tag (updating daily with the date, so as to give the impression to google that the content is always changing) "

now, we monitor all of our stats, rankings, etc and in the local industry, home construction, we dominate the area in blog and website rankings, etc. We have a pretty well optimized site, blah blah

But, we are always looking at ways to improve and this one is not known to me I admit.

So, can anyone expand on what this SEO person is suggesting? I assume it is some sort of php script? any examples? any truth or thoughts?

thanks.
