Activity number way off

Hello, I haven’t tried WoW Forums with another browser other than Firefox – As of yesterday, On all boards on here, they all say like 1 Day since last posts. This board says 3 days for the top board thread. Just wondering if anyone if noticing this

Right after I posted this, It says I posted this 1d ago when really it was moments after. Wha kind of time-travel is this??
