# dropLeading

The drop leading zeroes formatting behavior. Units whose values are 0 are dropped starting at the beginning of the sequence. Units continue to be dropped until a non-zero value is encountered. For example, when days, hours, minutes, and seconds are allowed, the abbreviated version of ten minutes is displayed as “10m 0s”.

## Declaration

```swift
static var dropLeading: DateComponentsFormatter.ZeroFormattingBehavior { get }
```
