Uses simplified shapefile fromtimezone-boundary-builder

GeoJson Simplification done withmapshaper

• The timezone shapefile is embedded in the build binary
• Supports overlapping zones
• You can load your custom geojson shapefile if you want
• Sub-millisecond lookup even on old hardware

• Shapefile is simplified using a lossy method so it may be inaccurate along the borders
• This is purely in-memory. Uses ~50MB of ram
