Wrong modified date

I’m using %asset_updated_rfc2822-dateonly% to display page last updated in a page footer. It’s set up in the parse file and applied to every page. It works fine on every page but our home page. When it is served as http://baseurl/ this value is incorrect (currently showing a September date) but when it is served as http:/baseurl/home/ the value is correct (updated today). We’re running Matrix 3.12.4.

That’s because http://baseurl/ is showing you the last updated date of your Site asset, not the home page asset it’s actually displaying.

I figured that, I guess my question should have been what's the best way around the problem, remap http://baseurl/ to http://baseurl/ on the /home page asset?
