What's a good way to format a citation to a MathOverflow post in a paper? Here is a first draft (with hyperlink, and assuming it's reference number 16, say), but maybe people can think of improvements:

[16] Pietro Majer, answer of April 8, 2014, 17:26pm HST to MathOverflow question 162724, Smooth convex extensibility of combination of two line segments.

(Related question: does the software know my time zone when it displays the time of day of an answer on screen?)
