We've somewhat started a cleanup, but being on a tablet, we can't do it fully.

Back when we designed it, we intended to have stamps for both start and end of posts, but people struggle enough with just one stamp per post. 

There are two active timestamps in the continuum. Kaggath and Memory. 
Six hours, forty-five minutes for Kaggath (roughly) 
Three days, five hours for Memory (also roughly)
