Description: Input latitude and longitude values or an 'sf/sfc' POINT
object and get back the time zone in which they exist. Two
methods are implemented. One is very fast and uses 'Rcpp' in
conjunction with data from the '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:
. The
package also contains several utility functions for helping to
understand and visualize time zones, such as listing of world
time zones, including information about daylight savings times
and their offsets from UTC. You can also plot a time zone to
visualize the UTC offset over a year and when daylight savings
times are in effect.
