Skimming the ticket comments, it smells like an idea that, ten weeks after Google's compile, a given release will start throwing SSL cert handshake alarms for at least some major websites.

Anybody that does not permit Chrome to auto-update might anticipate many intrusive SSL security warnings, every 10 weeks or less.

While you may have downloaded and installed Chrome on a given date, the download's compilation timestamp could be any point up to ten weeks in the past?

All because anti-virus?
