Mine were way off until I bought logten pro, but generally, I've never needed to know "day" hours, just night. If you really are curious, i guess, then TT-night=day tt.
There is alot of different "parameters" some companies want, like ME night.. those are fun.
No clue, bud. Can't recall where I saw it, but it was a question on the application. Seemed useless to me too.. But that's why I love my LogTenI have SE Day/Night, ME day/night.. Just in case!
weird. have never seen that in all my years.
