If I need an ETA for a destination I display the flight plan page - which has ETAs on it - on one of the GPSs. If I have a requirement to be somewhere by a certain time (Time On Target, as the mil. blokes say) then I play silly buggers with the power until ETA=TOT.
In most of the planes I fly, I have 2 x GPS each with time (selectable between UTC & whatever I want) & flight plan displays, a MFD with flight plan & time shown in local & UTC, pilot & co-pilot clocks, my watch which shows both UTC & local, his (or her) watch, and our cellphones. Not sure, but I think the EHSI in one plane can also show time. Not sure about the last one - I've had it set for what I want last 5 years.
I'm really struggling to understand why I'd need yet another time display.
