When I started to download it I limited the speed to around 2mb/s so that i could still download/upload other things and play some games with friends in the mean time. Its now 1 day and some hours since I started downloading it and I noticed that the elapsed time doesn't display properly.
Screen (it's in German but everyone should know the layout :P):
So the "Verstrichene Zeit" should theoretically look like "Verstrichene Zeit: 1:12:24:49" but instead it says "Verstrichene Zeit1, 12:24:49"
By the way the remaining time showed it correctly but obviously shows only some minutes remaining now.
I use WinSCP 5.7.6 (Build 5874) with the Commander Interface on Windows 7 Ultimate 64Bit.
