Specs
get_metadata(String.t()) :: {:ok, Zoneinfo.Meta.t()} | {:error, atom()}
Return Zoneinfo metadata on a time zone
The returned metadata is limited to what's available in the source TZif data file for the time zone. It's mostly useful for verifying that time zone information is available for dates used in your application. Note that proper time zone calculations depend on many things and it's possible that they'll work outside of the returned ranged. However, it's also possible that a time zone database was built and then a law changed which invalidates a record.
