Pebble.Alarm

Query the next scheduled system alarm.

Use next to show an alarm indicator on a watchface. The callback receives the UTC unix time in seconds, or -1 when no enabled alarm is scheduled.

import Pebble.Alarm as Alarm

type Msg
    = GotNextAlarm Int

init _ =
    ( model, Alarm.next GotNextAlarm )

update msg model =
    case msg of
        GotNextAlarm utcSeconds ->
            ( { model | nextAlarm = Alarm.toPosix utcSeconds }, Cmd.none )

This API needs firmware that implements alarm_service_peek_next. On older firmware the callback receives -1.

For a runnable example, use the watch-demo-time or watchface-digital project template in the IDE.
