Steps to reproduce the problem:
Like Firebug does. 
Also Firefox's http cache info page (about:cache?storage=disk) shows some details about cache (Fetch count, last fetched, Expires), Chrome doesn't.

What is the expected behavior?

What went wrong?
Calculating expires time is hard for human brain.

Did this work before? N/A
