No word about standard date format in lispguide.xml, how about http://www.w3.org/TR/NOTE-datetime

What steps will reproduce the problem?
1.

on_Required#Attention_Required

What is the expected output? What do you see instead?

I would expect the "Google Common Lisp Style Guide" to specify the format dates 
in comments should be in. My strong preference would be towards ISO 8601, to 
spare readers the bafflement which is 1/2/3 or 03.02.01.

The only mention of date is in the example below.
While "November, 2012" is unambiguous enough, it leaves the reader with no 
recommendation for representing specific dates or date-time.

Here is the excerpt:

Be specific when indicating times or software releases in a TODO comment:

;;--- TODO(brown): Remove this code after release 1.7 or before November, 2012.

What version of the product are you using? On what operating system?


Please provide any additional information below.

Using a standard date-time format would make it a lot easier for humans and for 
tooling to extract useful temporal information from program comments.
