I meant to send this a long long time ago... So here is the not-so-new news.
My friend Neil Barlett (Mr OSGi and Eclipse) spotted this mention of the ObjectLabKit (DateCalculator) as part of the proposal for the Open Financial Market Platform.
I can only say this: Wow!
I hope it succeeds as the main reason for creating this little library was our frustration at re-inventing the wheel so many times... I know a couple of big investment banks using it now, so it was worth it!
Back to work now...
