I am new to SWC, so maybe there's something I do not know, however...
I took a HyperSpace flight, and original ETA (that never varied the first two days) was to be some 5 hours ago, now.
Yet, since logging on to do my next 'move', my new ETA is 10 hours 53 minutes... which counts down when I remain "in cockpit", but then moves back to 10 hours 53 minutes as soon as I 'leave' and then return.
Thus, I am still at a 10h53 minute ETA (for about 5 hours now) when I should have arrived already (for those same 5 hours ago).
Same here, I was only about 8 hours from coming out of hyper about 20 hours ago, now the ETA is actually longer since they froze travel. Hopefully I won't fly into a sun.
