I’m not a fan of coloring for age of post. Usually the compromise is, when mouse hover it will show the actual date in a on hover popup. How about when clicking the time it changes to a timestamp (and back) or while mouse is hovering / touching the time it changes on the fly (without any hover tip, Edit: I just realized that most people don’t use a mouse on their phone :D also this would require dynamic changing with JavaScript).
I think the compromise is a visual indicator of age - color or an icon indicating recency, in addition to a good old fashioned date timestamp.
