What's up with Google's secret signed time “CheckGoogleSignedTime”

This appears to be the metric that Chrome for Android uses to track how long it takes to verify code signing on downloaded APK's. Or possibly does, rather—open source Chromium doesn't reference the metric at all and it would take decompiling Chrome for Android to know for certain if it's used there or not.
Look at the context. I think google is not trusting ntp or the client system time.

Something to do with shiny new database of Google.
The database that assumes people access google from multiple different time frames?
What is it? Where can I read more?
