I agree with the BDFL. I have always heard "wallclock" as referring to the clock on the wall (that's what the words mean, after all). When this term became current that meant an *analog* clock that did not automatically update for daylight savings time, so naturally if you measure an interval using it it is equivalent to "real time". However, to my mind the implication of the term has always been that the actual time value returned by a 'wallclock' function can be directly mapped to the time shown on the clock on the wall (assuming the computer's clock and the clock on the wall are synchronized, of course). Heh. Come to think of it, when I first encountered the term it was in the context of one of the early IBM PCs running DOS, which means that the computer clock *was* set to the same time as the wall clock. Thus regardless of what Wikipedia thinks, I think in many people's minds there is an inherent ambiguity in what the term means. If you use it to measure an interval, then I think most people would agree automatically that it is equivalent to "real time". But outside of interval measurement, there is ambiguity. So I think the definition in the PEP is correct. --David _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
