FFF - I have once logged 0.1 hrs for a non-departure flight!
It was my solo QXC, when I taxied to the hold, did power checks and found that I had a power drop on one mag. Asked ATC to get my CFI to meet me in the club a/c parking and taxied back (he didn't come out, so I had to shut down, walk to the club, drag him out, etc which all took around 30 mins). He then did all sorts of weakening the mixture, high revs sort of tricks and it still dropped on one mag. He told me 'it'll be alright - just go with it' and was a little miffed when I refused. Finally convinced him to let me use another a/c and got on with it, but was around an hour late setting out on my QXC.
Out of sheer cussedneess, I decided to log some time for the taxi out / back!!
