# lockDate

Returns the time the receiver was acquired by any of the NSDistributedLock objects using the same path.

## Declaration

```swift
var lockDate: Date { get }
```

## Return Value

Return Value The time the receiver was acquired by any of the NSDistributedLock objects using the same path. Returns nil if the lock doesn’t exist.

## Discussion

Discussion This method is potentially useful to applications that want to use an age heuristic to decide if a lock is too old and should be broken. If the creation date on the lock isn’t the date on which you locked it, you’ve lost the lock: it’s been broken since you last checked it.
