# CFTimeZoneCopyAbbreviationDictionary()

Returns a dictionary holding the mappings of time zone abbreviations to time zone names.

```
func CFTimeZoneCopyAbbreviationDictionary() -> CFDictionary!
```

## Return Value

A dictionary containing the mappings of time zone abbreviations to time zone names. 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

More than one time zone may have the same abbreviation. For example, US/Pacific and Canada/Pacific both use the abbreviation “PST.” In these cases this function chooses a single name to map the abbreviation to.
