1-2 weeks for Sigils, 3 weeks of waiting for 3k, maybe 4 if you happened to need the Chimera at the start of the lockout like I did on my Hunter, 3-5 weeks for Secrets, 3-5 weeks for Runestones and Celestials.
All in all 10-14 weeks, which is a pain considering the cloak is mandatory for anything past Normal essentially.
Shame you can't kill bosses for Secrets and then kill them again for Runestones ; /
