On a much more minor note, but a similar problem, Fitbit's sleep tracking still doesn't work with the daylight saving time change. It somehow manages to both think that it lost an hour of data in the middle of the night (represented by a grey bar hour with no pulse tracking) and think the night was an hour shorter than it actually was (the final data point, which was actually measured at 5:54am on the new clock and 6:54am on the old clock, is recorded as 4:54am). I'm not quite sure how they managed to get time handling that wrong, but it amuses me twice a year. Thankfully, the sleep tracking is basically a toy with no real medical significance and useful mostly for personal amusement. But Fitbit probably has more funding and engineering resources to fix problems like this than a lot of medical device companies, which is terrifying. -- Russ Allbery (eagle@eyrie.org) <http://www.eyrie.org/~eagle/>
