Create an empty cache of time‐zone information that will use the specified `loader` to populate the cache, as‐needed, with time zone information. Optionally specify an `allocator` (e.g., the address of a `bslma::Allocator` object) to supply memory; otherwise, the default allocator is used. In order the populate the cache for a time zone identifier, `loader` must return a `Zoneinfo` object that is well‐formed (see `ZoneinfoUtil::isWellFormed`) and whose `identifier` matches the supplied time zone identifier.
