Talk:Midnight Geohash
From Geohashing
Revision as of 07:30, 25 January 2009 by imported>Robyn (Any midnight attached to the day should satisfy.)
Unclear and self-contradictory timing rules
Someone brought it up on the IRC and taking a closer look, the rules are somewhat self-contradictory. Currently it says:
- First midnight after announcement
- First night after announcement
- 0:00 east of W30, 24:00 west of W30
There are two issues with that definition:
- On weekends, the first midnight after announcement is 0:00 also west of W30, which would mean that there are different times to go there depending on the day.
- In the very east - like, Australia and New Zealand - the coordinates are announced around or after midnight, making it impossible to go at 0:00.
I want to propose a redefinition like follows:
- 24:00 on all days for W30 to W180
- 0:00 on all days for W30 to E90 (border debatable)
- 24:00 on all days for E90 to E180
At E90 the coordinates are announced around 20:30, still leaving a realistic chance to start on the same evening. This border may be debatable, though. Setting the border to the timezone border UTC+8/UTC+9 would create places where only half an hour is left on weekdays, though.

- Sounds good to me. At the moment it seems to imply I should do my sunday hash on friday night. :| Juventas 22:44, 24 January 2009 (UTC)
- Why not change the rules to just "in the middle of the night" so that the hasher can freely choose whether he/she wants to be at the hashpoint at either 0:00 or 23:59? I don't see a reason why we should limit the options at all. --Ilpadre 07:24, 25 January 2009 (UTC)
- I'm with Ilpadre here. The timing on when the coordinates become available is so variable from time zone to time zone that whatever the intention of the original proposal was, it is lost in translation. I think if you're at the coordinates at midnight, whether that is the very beginning or the very end of the appropriate day, you have succeeded. Perhaps the original intention WAS to put time pressure on the geohash. if we were to create an achievement for reaching the geohash in a minimum time after the announcement, what should the requirement be? One hour? Two? Half an hour? -Robyn 07:30, 25 January 2009 (UTC)
