Hello Leadsled,
I understand what you're driving at, but in reality the company and regulator of the country in which I work have no interest in my logbook at all, as they already have the data and can apply their own rules to the stick time / rest time thing on URL trips.
The next time that my logbook would be looked at, would be in Europe I expect - if I add ratings to my EASA licence or if I decided to change jobs one day. I know from others experiences that the euro authorities can get a bit sniffy about time logged elsewhere which is not in accordance with euro rules - requiring the logbook to be re-written, that sort of thing.
That's what I am trying to avoid, that's all.
