# Date.FormatStyle.Symbol.TimeZone

A type that specifies a format for the time zone in a date format style.

## Declaration

```swift
struct TimeZone
```

## Overview

Overview The type Date.FormatStyle.Symbol.TimeZone includes static factory variables and methods that create custom Date.FormatStyle.Symbol.TimeZone objects:  |   |   |   |   |   |   |   |  To customize the hour format in a string representation of a Date, use timeZone(_:). The following example shows a variety of Date.FormatStyle.Symbol.TimeZone format styles applied to a date. let meetingDate = Date() // Feb 9, 2021 at 7:00 PM

meetingDate.formatted(Date.FormatStyle().timeZone(.specificName(.short))) // CDT meetingDate.formatted(Date.FormatStyle().timeZone(.specificName(.long))) // Central Daylight Time

meetingDate.formatted(Date.FormatStyle().timeZone(.genericName(.short))) // CT meetingDate.formatted(Date.FormatStyle().timeZone(.genericName(.long))) // Central Time

meetingDate.formatted(Date.FormatStyle().timeZone(.iso8601(.short))) // -0500 meetingDate.formatted(Date.FormatStyle().timeZone(.iso8601(.long))) // -05:00

meetingDate.formatted(Date.FormatStyle().timeZone(.localizedGMT(.short))) // GMT-5 meetingDate.formatted(Date.FormatStyle().timeZone(.localizedGMT(.long))) // GMT-05:00

meetingDate.formatted(Date.FormatStyle().timeZone(.identifier(.short))) // uschi meetingDate.formatted(Date.FormatStyle().timeZone(.identifier(.long))) // America/Chicago

meetingDate.formatted(Date.FormatStyle().timeZone(.exemplarLocation)) // Chicago

meetingDate.formatted(Date.FormatStyle().timeZone(.genericLocation)) // Chicago Time

If you don’t provide a format, the system formats a timezone using the short specificName(_:) static function with the width Date.FormatStyle.Symbol.TimeZone.Width.short. For more information about formatting dates, see the Date.FormatStyle.
