I'm trying to create an alarm using the new Alarm class in the Windows Phone 7.1 SDK

I'm able to get it to work but the alarm doesn't seem to be going off at the time i've set.

Alarm alarm = new Alarm("MyAlarm")
        {
            Content = "Alarm!",
            BeginTime = DateTime.Now.AddSeconds(seconds),
        };
ScheduledActionService.Add(alarm);

解决方案

The remarks in MSDN say

The action will not be invoked before the begin time has been reached.

(emphasis mine)

There is no guarantee on the alarm being called at the exact second specified. I would expect there to be the possibility of the alarm being triggered up to a few seconds after the specified time, but not before.
