Summary

  • getFuzzyTimezoneFromTile([3, 5, 4]) returned America/Denver. That tile is mostly central time.
  • The vote used each zone's first historical abbreviation, which is LMT almost everywhere, so the last child won. It now uses the abbreviation at the current time. Los Angeles at zoom 5, 6, and 7 is still America/Los_Angeles.

Test plan

  • Red: the tile came back as America/Denver.
  • tap 53 passing.

Tile 3/5/4 came back as America/Denver. The current abbreviation is Central, so it is now America/Chicago.
