I'll make it short and simple.
I think Staff should periodically set down time skips to accurately portray the movement of time for the entire site, say like making an official announcement that the accepted board-wide year is 855 ABY or 856 ABY etc etc etc
Maybe every year we advance by 3-4 years, or whatever is deemed necessary by staff.
I personally think that since it's been so long since the last timeline update, we should advance Chaos' time by a good 10 - 15 years before toying with the idea of yearly time advances or something along those lines.
Cuz as far as the official lore goes, it's still 851 ABY with the incursion and stuff.
Food for thought.
