I see what you are saying. I have just bought a replacement log book as I messed an entry up early on and wanted it to be right so was just asking. I also wanted to use 1.05 hours/mins instead of 0.8 decimals etc as it makes more sense.
I have decided on using local time (for ease when operating locally and so they match the times in the training record) but with BST written above the times so I know which are BST and the rest are UTC/GMT.
