# MusicEventIteratorSetEventTime(_:_:)

Sets the timestamp for the event at a music event iterator’s current position.

## Declaration

```swift
func MusicEventIteratorSetEventTime(_ inIterator: MusicEventIterator, _ inTimeStamp: MusicTimeStamp) -> OSStatus
```

## Parameters

- `inIterator`: The music event iterator whose current event you want to change the timestamp of.
- `inTimeStamp`: The new timestamp for the event, in beats.

## Return Value

Return Value A result code.

## Discussion

Discussion After calling this function, the music event iterator remains positioned at the same event. However, because the event has been moved to a new location on the iterator’s music track, the iterator may no longer have a next or previous event. You can test this by calling MusicEventIteratorHasPreviousEvent(_:_:) and MusicEventIteratorHasNextEvent(_:_:).
