when flying in the USA we used only hobbs times.... and all the Jeppesen logbooks I know of don't allow any room for take-off and landing times. These hobb times are the flight times used for the records (I always got laughed at when I wanted the clock-times to use as flight times).
Until we had JAR-FCL (began this past May1), we recorded here in Germany as flight times the actual take-off (lifting from the runway) to landing (on runway) times. These times were recorded in our personal logbooks and in the airplane logbook. The hobbs were also recorded for our payment (running usually 1.00 = 1 minute).
Now my question to all you JAR-FCL experienced people: do you look at your watch as soon as you leave your parking position to taxi toward the runway and again after you park and then record these times in your logbooks? The tower obviously only records actuall take-off and landing. I agree that I'm the responsible person as soon as that aircraft moves (PIC), so it should be in my books. And I also know that some pilots even record times when they're a passenger

but there will always be people misusing the system.
Looking forward to some answers....
