# resetSystemTimeZone()

Clears any time zone value cached for the system property.

## Declaration

```swift
class func resetSystemTimeZone()
```

## Discussion

Discussion If the app has cached the system time zone by accessing the system class property, this method clears that cached value. If you subsequently access the system class property, a new time zone object is created and cached.
