Country-specific time-zone notes
- The territory mapping contains a single named IANA zone.
- All current offsets are whole-hour offsets.
- No listed zone changes its clock during 2026.
IANA identifiers and territory associations come from the bundled IANA zone.tab data. Current offsets and transitions are calculated from the time-zone rules available to this build and refreshed in your browser. Directory cities are representative locations, not legal boundary definitions. See the methodology and data sources.
