If the league is following the official series schedule, in my opinion greater effort should be taken to try an align the start time with the official time. For example the season finale at Suzuka the official start time was around 5 p.m yet the league race started somewhere around 9 p.m, complete darkness at a track that has no official night "mode". Not only does this affect the drivers, it also affects the broadcast, being very hard to tell whats going on at times. So my proposed solution would be to set the practice start time earlier. E.g if the official start time is 6 p.m set the practice to start at 3 p.m, this would compensate for the 2h 40m practice session and the 15min qualifying and would more closely align the times.
This is purely my opinion, I'm not aware if the this is intended by the league although it does not seem to be.
