I came across this class the other day as it seems to offer functionality useful to me. However its in the com.adobe.fiber.runtime.lib package, which I was unaware of. The comment in help says:
"The DateTimeFunc class defines the implementations of the expression runtime functions for Date and Time functions in the Adobe application modeling language."
So I'm guessing this has something to do with data modelling authoring wizards. Seems a bit odd that an Adobe authored Actionscript class that could add very useful functionality to Date such as dateDiff() is hidden away in this backwater. Is this stuff usable by mere mortal Flex developers? Is the source available anywhere, or is it compiled into some LC swc? I'm probably going to have to implement a dateDiff and some other utils to make Date more useful, but don't want to reinvent the wheel.
