I noticed that the time picker would not parse a 3 or 4 digit time w/ am/pm (that doesn't have a ":" separator) even though there wouldn't be any ambiguity based on the parseFormat array.  I was told that the picker doesn't officially support any time parsing that doesn't contain a colon and if some work without a colon it is by chance.

This vote would be for more thorough format parsing on the picker controls.  The ones I specifically noticed were failures to parse "hmmt", "hmmtt".  See this ticket for more info and a dojo example.
