Niue standard time

Seen on the web page of Fun with Algorithms: “A full paper should be submitted by January 23, 2012 , 11:59 pm, Alofi, Niue, standard time.”

The conference is in Venice, Italy, and it’s organized by Italians, so why Niue?

Alofi is the capital of Niue, an island country in the South Pacific, where the time is 11 hours behind UTC. (Although Niue is in free association with New Zealand and uses New Zealand currency, it is not the same day in Niue as in New Zealand; New Zealand is 12 hours ahead of GMT, or 23 hours ahead of Niue.) This is the time zone furthest behind UTC that actually contains any population; there’s a UTC-12, but it only contains some uninhabited islands. So presumably the choice was made so that if people acted as if the deadline was January 23, 2012, 11:59 pm, their local time, they would still get their papers in on time.

American Samoa is in the same time zone; the independent county of Samoa is UTC+13, one day later. (They were UTC-11 until they skipped December 30, 2011; this moved them from being three hours behind the US west coast to being three hours ahead of the Australian east coast.) I can’t find any uses of “Samoa time” being used the same way.

There is at least one other use of “Niue standard time” in a non-Niuean context.

Via David Eppstein. I have nothing to do with this conference, other than that I support fun.

  1. Yes, there have been CS conferences which have used American Samoa time. We sure didn’t treat it as a midnight deadline. But it was pretty awful, since staying up till 7am in Eastern Time is no fun.

    I think I recently read somewhere about American Samoa switching sides of the date line, so that it is no longer the latest midnight on the planet (but is instead the first place where it’s the new day).
