This user earned the Time-traveller achievement
by reaching both the ({{{latitude}}}, {{{longitude}}}) and ({{{latitude2}}}, {{{longitude2}}}) geohashes at exactly {{{time}}} on {{{date}}}.

The achievement can be claimed if you venture to two or more geohashing locations on the same day and the same local time.

If you don't own a time-machine, you could ...

  • cross a time-zone border.
  • take advantage of the autumn daylight saving clocks change.
    • Geohashers nearer the equator are at a disadvantage because they have further to travel east or west.
    • Geohashers near longitude 0 or 180 might be lucky and not have to travel far at all.
  • get lucky.
    • If, at the equator, the longitude is less than +/- 0.000036° you will be in the circle of uncertainty for two hashpoints simultaneously.
    • Further from the equator this longitude can be calculated from 0.000036 / cos(Latitude). The poles are singularities!
    • A similar effect applies at longitude +/- 89.999964°.

Of course, as usual, you need to upload photos of yourself containing the necessary proof.

Winners

Woodveil was at the 2009-03-08 33 -84 and 2009-03-08 33 -85 hashes at 12:39 local time.
B2c and Patrizius were at the 2013-10-27 47 13 and 2013-10-27 47 12 hashes at 02:09 local time. It was a DST time travel.
Micsnare and B2c were at the 2014-10-26 47 14 and 2014-10-26 47 13 hashes at 02:01 local time. It was a DST time travel. Again ;)
