No one seems to have pointed out that the requirements for logging time (be in it decimals or minutes, either is fine) are different for the airframe/engine/prop and the pilot. The pilot requirements have already been stated, but for the mechanics, the times required are take off to touch down. Consequently you can quite legally have more 'personal' time logged than you pay for. None of this means that you should fiddle your figures for the benefit of your hours/wallet, or the detriment of the club, but anything over 10 or 15 minutes difference between the two would raise my eyebrows if I was in a position to be checking
