I was just playing around with Chrome and was wondering if anyone know what does the number in %USERPROFILE%\Local Settings\Application Data\Google\Chrome\User Data\chrome_shutdown_ms.txt mean ?

Everytime I shutdown chrome, it will change, so I'd expect the number inside it to mean *the number of milliseconds it takes to shutdown chrome..

But it doesn't seem to be so because my number writes 1000+, sometimes even 2000+ and yet it doesn't actually even take a second to shutdown chrome, so obviously that number couldn't be the amount of milliseconds it takes to shutdown chrome.

Does anyone know what does that number mean?

The chrome window disappearing does not mean that chrome has shutdown , if you check you task manager u can see that chrome process are still running after yo have closed the browser – Shekhar Dec 27 '11 at 11:04
@Shark hey yes I'm aware of that but even the Chrome process had been terminated within < 500 milliseconds hence the question – Pacerier Dec 28 '11 at 6:55
You should ask on the Google Chrome forums. – surfasb Dec 28 '11 at 10:39

According to the chromius sources, which can be searched here for chrome_shutdown_ms.txt, this is exactly the shutdown time of Chrome (at least, for a part of its processes). If you see that chrome processes disappear from process list faster than the logged time, then there could be a bunch of reasons for this, but they are hard to deduce without additional testing.
