  1. Mark adm_0 boundary lines used in TZ boundary.
  2. Mark adm_1 boundary lines used in TZ boundary.
  3. Add select adm_2+ boundary lines used in TZ boundary.
  4. Match up the existing TZ boundary lines with above 3 so the ends snap.
  5. Create coastline buffer file for countries that don't already have one.
  6. Create build script to create scale rank version of TZ boundary using above ingredients + WGS84 bbox. This will match, which includes named features and country and sub-country zones that are there for historic or housekeeping reasons (like zone names), but often share the same UTC offsets. Equivalent of adm_0_map_units?
  7. Extend build script to dissolve above into the standard view by zone live on Natural Earth now.
  8. Make the building ingredients available as a separate download.
  9. Add the scale rank version as a separate download.

Note: there is some disagreement with Natural Earth and Eric Muller's version in the hinterlands. Natural Earth's version should be considered right in most cases (looking at Siberia in particular). Muller's take on China by Hainan is odd.
