lutz (0.2.0)

Look Up Time Zones of Point Coordinates.

Input latitude and longitude values or an 'sf/sfc' POINT object and get back the timezone in which they exist. Two methods are implemented. One is very fast and uses the 'V8' package to access the 'tz-lookup.js' 'Javascript' library (). This method also works outside of countries' borders and in international waters, however speed comes at the cost of accuracy - near time zone borders away from populated centres there is a chance that it will return the incorrect time zone. The other method is slower but more accurate - it uses the sf package to intersect points with a detailed map of time zones from here: .
