Well, ClubJuggle disagreed with me back in 2004 on this.


That was 4 years ago. Ample time for mastery of the addition and subtraction required to figure out someone's local time based on their offset from GMT.


Hence needing to know someone's real time zone (residence) offset to UTC.


This does not follow. Your argument is not logical:

That depends on where your real time zone is. UTC is ahead of server time. If your real time is ahead of UTC then you could potentially take a photo prior to the announcement of the challenge for use in the challenge as you have intentionally turned your camera time back.


If I live in Japan (time zone UTC+9), the "problem" you pose is possible. However, it is clearly stated that the challenge starts at 00:00 US Eastern time (UTC-5 w/DST) -- which is 13:00 or 14:00 Japan time depending on whether DST is in use. There is no difference between me using UTC time someone living in Iceland.

Also, why should my geographic location matter? DPChallenge does not take local time into account for deadlines or challenge start times, so local time is completely insignificant -- in fact, you must convert from the "absolute" time of US Eastern into your local time to determine when the challenge begins and ends in your local time zone.


It takes local time into account when validating photos. So as long as it is known what the your local UTC offset is then setting your camera to UTC does not matter.

OK, that seems fair, consistent, and simple.
