Within the UK it is usual in PPL logbooks to have a single column entitled "Pilots Operating Capacity", "Dual" (this column does not define the role of the pilot and is used only to record the duration).and also the "Pilot in Command" column (these last two are duplicated to record flight at night) There are also many other columns, of course, but they are not in question here.
In the single operating capacity column you enter your role in the flight:i.e. pilot in command (P1*), pilot in command supervised (P1/s*), pilot under training (PUT*). You then enter into either the "dual" or the "PIC" column the duration. .Remember when entering the times and the duration a "flight" commences when the aircraft first moves under its own power with the intention of flight until it comes to a full stop after the flight.
Many clubs use a Datcom meter, which records the flight duration based on the engine time in tenths of an hour, but for charging purposes. This type of meter is activated on start up (oil pressure) and stops on shut down, It is common to use this duration for pilot logging purposes. To be fair It is churlish to nit pick on the differences that exists for simple aircraft operations. There are other types of meter in use that will record time differently.
* there are a range of abbreviated terms which have the same meaning, it matters little and does not cause concern. P1/s can only be logged when flying single pilot aeroplanes, for a successful skill test with an examiner.
