# CFTimeZoneCreateWithName(_:_:_:) Returns the time zone object identified by a given name or abbreviation. ``` func CFTimeZoneCreateWithName(_ allocator: CFAllocator!, _ name: CFString!, _ tryAbbrev: Bool) -> CFTimeZone! ``` ## Parameters `allocator` The allocator object to use to allocate memory for the new time zone. Pass `NULL` or kCFAllocatorDefault to use the current default allocator. `name` The name or abbreviation of the time zone to obtain. The name may be in any of the formats understood by the system, for example “EST”, “Etc/GMT-2”, “America/Argentina/Buenos_Aires”, “Europe/Monaco”, “US/Pacific”, or “posixrules”. For a complete list of system names, you can see the output of [`CFTimeZoneCopyKnownNames()`](/documentation/CoreFoundation/CFTimeZoneCopyKnownNames()). `tryAbbrev` If `false`, assumes `name` is not an abbreviation and searches the time zone information directory for a matching name. If `true`, tries to resolve `name` using the abbreviation dictionary first before searching the information dictionary. ## Return Value A time zone corresponding to `name`, or `NULL` if no match was found. Ownership follows the [The Create Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-103029). ## Discussion --- Copyright © 2026 Apple Inc.
