Ok, due to time constraints, I'll just consider this accepted. Feel free to continue expressing support, or point out any issues. -- relet 07:11, 28 February 2012 (EST)_

Do you think we can get the award for an alternate? - Robyn 21:17, 29 February 2012 (EST)

Oppose. Alternate locations are an ok means to make saturday meetups possible where they are desired by a certain local group, however, meeting up at some arbitrary location may be fun but isn't really geohashing, is it? There's no adventure involved, basically (Of course you can choose to add an adventure but it's not required and you can do that with any kind of trip). Also, alternate location meetups are only possible in regions where there even are enough people to get a meetup together. So, getting together an alternate meetup is a question of being part of a large enough local group, basically. On the other hand, I would fully support to give this ribbon out to people who seriously tried to get as close as possible to the hashpoint but failed for inaccessibility. --Ekorren 03:44, 1 March 2012 (EST)

Use UTC and not GPS Time[edit]

Should you be located at the hashpoint before 23:59:60 or after? I have just claimed for the leap second at 2017-01-01 52 0. I also visited 2016-12-31 52 0 but an hour earlier. Am I going to be stripped of my claim? It would be fun to be stripped by the geohashing community! --Sourcerer (talk) 03:22, 1 January 2017 (UTC)

And GPS time is 18 seconds fast relative to UTC just to add more confusion. --Sourcerer (talk) 03:41, 1 January 2017 (UTC)
IMHO this is pretty clear: "to earn the achievement by geohashing on a leap second you need to be at the coordinates at the exact time of the leap second", so as long as you were at the geohash at 23:59:60 UTC you can claim the achievement. --Crox (talk) 20:08, 1 January 2017 (UTC)
Hmmm. I suppose it's UTC that has leap seconds so you'd have to use UTC for the Leap Achievement. All my geohashing has been on done on GPS time, hence my confusion. But now I can claim a Gratuitous ISO Fail and and a Radio Yerevan. --Sourcerer (talk) 22:16, 1 January 2017 (UTC)
Actually, I think you're fine for one of your hashes. The GPS satellites send out information every 12.5 minutes about the difference between UTC and TAI, and I think most GPS receivers will use that in order to display something that is within a second of UTC.

At my first hashpoint it was the wrong time. At my second, it was the wrong place. I consider myself well and truly stripped of the Leap Achievement but it was fun and I learned a lot about clocks. I'll check to see if my Garmin eTrex 20 corrects for the GPS time difference but even if it does, I will still have been in the wrong place. The main result was walking through skeletal midnight winter woods surrounded by distant pyrotechnics, putting up foxes, deer and pigeons - wonderful! --Sourcerer (talk) 08:16, 2 January 2017 (UTC)
