Unfortunately although we have already created (and tested) an ACCT Bitcoin script that uses CLTV the UI side of things is what really takes quite a bit of time and we don't think that releasing an unfriendly and mostly manual implementation would be appealing to virtually anyone so the work to develop decent UI (for the Bitcoin side of things) and to improve the UI on the Qora side of things will take some time.

That being said I do think we should be able to end up with something that is user friendly and that will be very robust (an estimate at this stage is a little hard but I would certainly think that you could expect to see a release by mid-year with this functionality).
