# second(_:)

Modifies the date format style to use the specified second format style.

```
func second(_ format: Date.FormatStyle.Symbol.Second = .defaultDigits) -> Date.FormatStyle
```

## Parameters

`format`

The second format style applied to the date format style.

## Return Value

A date format style modified to include the specified second style.

## Discussion

Values of [`Date.FormatStyle.Symbol.Second`](/documentation/Foundation/Date/FormatStyle/Symbol/Second) are [`defaultDigits`](/documentation/Foundation/Date/FormatStyle/Symbol/Second/defaultDigits) and [`twoDigits`](/documentation/Foundation/Date/FormatStyle/Symbol/Second/twoDigits).

This example shows a variety of [`Date.FormatStyle.Symbol.Second`](/documentation/Foundation/Date/FormatStyle/Symbol/Second) format styles applied to a date:

```swift
let meetingDate = Date() // Feb 9, 2021 at 3:05 PM
meetingDate.formatted(Date.FormatStyle().second(.defaultDigits)) // 5
meetingDate.formatted(Date.FormatStyle().second(.twoDigits)) // 05
meetingDate.formatted(Date.FormatStyle().second()) // 5
```

If you don’t provide a format, the [`defaultDigits`](/documentation/Foundation/Date/FormatStyle/Symbol/Second/defaultDigits) static variable is the default format.

For more information about formatting dates, see [`Date.FormatStyle`](/documentation/Foundation/Date/FormatStyle).
