Date Picker Show & Tell Part 2

Looking at the wireframes for the time picker, I have been wondering 
about how you plan to distinguish between 12:00 noon and 12:00 midnight. 
I couldn't find an answer to this in the design pages.  Do you plan to 
have the AM/PM change to Noon/Midnight when exactly 12:00 o'clock is 
displayed?  This is probably the best way to get around the usual 
confusion on this topic, but it may also be worthwhile to do a bit of 
user testing as well.
