# postAlert

The duration applied after the alarm has alerted at least once and
moves back to the countdown state.

```
var postAlert: TimeInterval?
```

## Discussion

For example, this would be the snooze duration for an alarm.  A
timer with a repeat button could set this value to be the same as
`preAlert`, or it could leave the value as `nil`.  If the value is
`nil` we will use the `preAlert` duration for post-alarm countdowns.
