# init(abbreviation:)

Returns a time zone identified by a given abbreviation.

```
init?(abbreviation: String)
```

## Parameters

`abbreviation`

The abbreviation for the time zone.

## Return Value

A time zone identified by abbreviation determined by resolving the abbreviation to an identifier using the abbreviation dictionary and then returning the time zone for that identifier. Returns `nil` if there is no match for abbreviation.

## Discussion

In general, you are discouraged from using abbreviations except for unique instances such as “GMT”. Time Zone abbreviations are not standardized and so a given abbreviation may have multiple meanings–for example, “EST” refers to Eastern Time in both the United States and Australia
