tzdb_initialize() is intended to be called from a client package's .onLoad() as tzdb::tzdb_initialize() to ensure that the tzdb package has been loaded.

The function itself doesn't do anything. It is instead called for the side-effect of loading the tzdb package. This does two things:

  • The tzdb .onLoad() hook is run, which sets the path to the time zone database.

  • The callables in tzdb are registered, which allows them to be called from other packages.

tzdb_initialize()

Value

NULL, invisibly.

Details

There are alternative ways to ensure that tzdb is loaded. A client package can alternatively import a function from tzdb into its package with the @importFrom tag, or can call requireNamespace("tzdb", quiet = TRUE) from its .onLoad().
