    Fixes #17521. Return the dojox.date.timezone object in the define() function, so it isn't empty when loading it with require(). Finished migraiting dojox/date/timezone to dojo 1.9 syntax as well (no dojo.*).
Fix dojox/widget/ColorPicker's habit of always firing onChange when value is set.
Patch from neek, thanks! Refs #16908.
