The only real shortcoming I see here is that time isn't specified. The date format is determined by your system settings. Are you saying that's not the case for you? If so, what Linux distribution and version are you using?

Without knowing my locale, tell me this. What is this certificate's validity period?

* 11th June 2015 - 2nd April 2016
* 6th November 2015 - 4th February 2016

You can't. You'd guess right because of context at best. Like I said in the chromium issue, I'm a european who prefers english locales, but that doesn't mean this date format is comfortable to me - nor is it clear. There's quite a bit of discussion there and hopefully enough reasoning to switch to ISO or long form date format, take a look.

Thanks for filing the bug, but switching to long date format has already been done in Bug 443811 for Firefox 43.

For ISO 8601, see Bug 1053679.
