I have a huge list of times and would like to calculate an average or typical time. If I would just use the median (or other "normal" types of calculating an average), for example 23:59 and 00:01 would yield 12:00 when it should 00:00. Is there a better method?

    What would you like the average of the sample 00:00, 06:00, 12:00, 18:00 to be?2012-01-03

    @DidierPiau: It would be ok if it would yield anything or `undefined`. However my data samples are rather huge so that would be rather unlikely.2012-01-03

    My point is that you will stumble on the same problem with huge data samples, namely, these samples will be roughly evenly distributed on the unit circle. Then it is difficult to summarize the sample by anything else than a point near the center of the circle, which is meaningless because this will not be ON the circle... (Re-reading your post, I realize that even a median, whose existence you take for granted, seems difficult to define.)2012-01-03
