Yes, although the DateField component is terribly time-consuming/annoying when trying to choose a year that is more than 100 years back. I think the UI for this component needs to be revisited: holding down the arrow button is not really the optimal interface mechanism for this purpose. Another problem with way-back years and DateField is that DateField completely breaks on any years in the BC era (anything before 0, e.g. negative numbers).
Wow, I want to know why would you need a date that old
I wish the time component is more user friendly as has been done on Flex AIR.
