问题描述
我正在尝试使用 Windows Phone 7.1 SDK 中的新警报类创建警报
I'm trying to create an alarm using the new Alarm class in the Windows Phone 7.1 SDK
我可以让它工作，但闹钟似乎没有在我设置的时间响起.
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);
推荐答案
MSDN中的备注说
在开始时间之前不会调用该操作到达.
The action will not be invoked before the begin time has been reached.
(强调我的)
不能保证在指定的确切秒内调用警报.我希望在指定时间后的几秒钟内触发警报的可能性，但不会在此之前.
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.
