sieve date support?

[Kenneth Marshall]

I know the date extension to the sieve language was discussed
a while back. Is their any plan to add it to the Cyrus sieve
implementation? That would allow it to handle the largest
issue that our users face -- enabling/disabling vacation
on a predetermined schedule. Currently, they must remember to
turn it on when they leave and then remember to disable when
they return.
