About

Time zones primarily derive from the Central Intelligence Agency map of Time Zones, downloaded from the World Factbook website May 2012. Boundaries were adjusted to fit the Natural Earth line work at a scale of 1:10 million and to follow twelve nautical mile territorial sea boundary lines when running along coasts. Additional research was performed based on recent news to update several areas including the international dateline and time zone adjustments for Samoa and Tokelau and the discarding of daylight savings time in Russia.

Data attributes include time offset from Coordinated Universal Time (UTC, aka “zulu” time) and map color codes for a 6-up and 8-up styling.

Issues

Does not integrate completely with the ne_10m_admin_0_maritime_indicators and ne_10m_admin_0_pacific_grouping_lines due to countries with split zones and other particularities of mapping time zones.
