I figured it out, if anyone else wants to use this addon, update line 458 - 465 to the following:
Code:
if endTime then -- update statusbar if destination time is known
if totalTime - 2 > endTime then -- in case the flight is longer than expected
SetToUnknown()
endTime = nil
sb:Hide()
this:Hide()
endTime = nil
else
We kill it with sb:Hide() and this:Hide() as soon as the time goes 2 seconds the expected time.
It will require using a premade flight time database available here:
