Google Showing Update Time By Minute

I was doing a site:domain search last night and noticed Google is now giving the time of the last update or visit – by the minute. I will call over to Google and get a clarification but it is interesting either way.

One shows when the site may have been last spidered or updated, or when someone last visited the page.

I did a screen capture but they are still there. Though it seems to be for the more visited sites, I am still playing to get an idea of what is causing this.

Update: Barry Schwartz showed me this…. guess I was six months late on this one.
