Roland,
I added my comments to the Clarizen Success article here:

DATE FILTERS posed a problem for me and I believe this CR you filed is based on some previous comments I made, although I never commented on this one before. Finally, I also gave Peter some "props" for bringing this up eight years ago here:

Everyone, make sure you VOTE UP; so Clarizen takes notice of "critical mass" surrounding a specific feature request.
