# significantTimeChangeNotification

A notification that posts when there’s a significant change in time.

```
nonisolated class let significantTimeChangeNotification: NSNotification.Name
```

## Discussion

The system posts this notification when, for example, there’s a change to a new day (midnight), a carrier time update, or a change to, or from, daylight savings time. The notification doesn’t contain a user info dictionary.
